G and determine P(R > G). This site uses Akismet to reduce spam. Classic probability . Therefore, the concept of classical probability is the simplest form of probability that has equal odds of something happening. 1-9 A red die has face numbers {2, 4, 7, 12, 5, 11}. Prior to this, dogs were a fairly neutral stimulus. Need help with a homework or test question? Note that we do not allow for all fiv. Classical Probability: The classical approach to probability is one of the oldest and simplest school of thought. According to the above definition, the coin toss event is an example of a classical probability, since the probability of the result being expensive or being a stamp is equal to 1/2. Check out these fun examples of probability in everyday situations. For example, when we toss a coin, either we get Head OR Tail, only two possible outcomes are possible (H, T). He asked her to draw a card from the 12 cards. The odds of rolling a 2 on a fair die are one out of 6, or 1/6. For example, the probability of a male Englishman being between five and six feet tall is judged simply from the empirically given distribution of heights in the population." Imagine you want to know the probability of the outcome of your tossed coin being “head”. You’ll need something more complicated than classical probability theory to solve them. The classic probability is that in which all possible cases of an event have the same probability of occurring. Selecting bingo balls. You can only use classical probability for very basic events, like dice rolls. Classical Probability is based on the assumption that the outcomes of an experiment are equally likely, for example, rolling a fair dice. 2. “f” is the frequency, or number of possible times the event could happen. That is, 0 ≤ P(A) ≤ 1. divided by the number of possible outcomes (1,2,3,4,5,6). EMPIRICAL OR STATISTICAL PROBABILITY EXAMPLE 3.3.10 A carnival game requires the contestant to throw a softball at a stack of three "bottles." To understand better the general definition of classical probability we are going to take the next example: there is a group of people which are listed by numbers between 1 and 10, and one of them are going to get a price, the decision will be make by picking a random number between 1 and 10 and the person with that number is going to be the winner. This lesson shows you how to compute for the probability of an event under the classical probability. Gambling problems are characterized by random experiments which have n possible outcomes, equally likely to occur. Subjective probability is the only type of probability that incorporates personal beliefs. Important Points (a) The probability of an event lies between 0 and 1, both inclusive. Classical probability is a simple form of probability that has equal odds of something happening. Each numbered ball has an equal chance of being chosen. Classical Probability examples. Opinion Poll Example: It is desired to know what the probability is that someone in a particular population favors blue over other colors. The Classical Model of Probability . The probability of a simple event happening is the number of times the event can happen, divided by the number of possible events (outcomes). Example 2: Another example of classical probability would be tossing an unbiased coin. They are speaking in mathematical probabilities. We will go over this concept in Examples 2 and 3. imaginable degree, area of Her favorable outcome is a king and there are 4 kings in Jonathan's hands. There are many other examples of classical probability problems besides rolling dice. Use the data to answer each of the following questions. Classical Probability Probabilities are assigned to individual events. These examples include flipping coins, drawing cards from a deck, guessing on a multiple choice test, selecting jellybeans from a bag, and choosing people for a committee, etc. Other Examples of classical Probability. Classical probability theory on ℝ or ℝ k is mostly concerned with the limiting behaviour of the partial sum sequence (S n) n ⩾ 1.The most important and famous results are the (strong) law of large numbers (LLN), the central limit theorem (CLT) and the law of the iterated logarithmic (LIL) which, for real-valued random variables, may be summarized in the following way. Similarly, the probability of getting all the numbers from 2,3,4,5 and 6, one at a time is 1/6. Based on how poorly the … No. The typical example of classical probability would be a fair dice roll because it is equal… The classic probability is that in which all possible cases of an event have the same probability of occurring. 1. A great book, one that I will certainly add to my personal library. On tossing a coin we say that the probability of occurrence of head and tail is \(\frac{1}{2}\) each. Classical Probability Event A result of an experiment Outcome A result of the experiment that cannot be broken down into smaller events 4 Sample Space The set of all possible outcomes Probability Event Occurs # of elements in Event / # Elements in Sample Space Example –flip two coins, find the probability of exactly 1 head.

Classical probability can be used for very basic events, like rolling a dice and tossing a coin, it can also be used when occurrence of all events is equally likely. The classical definition or interpretation of probability is identified with the works of Jacob Bernoulli and Pierre-Simon Laplace.As stated in Laplace's Théorie analytique des probabilités, . For example, natural events like weights, heights, and test scores need normal distribution probability charts to calculate probabilities. There are many other types of classical probability problems besides rolling dice. What is probability? Classical (sometimes called "A priori" or "Theoretical") This is the perspective on probability that most people first encounter in formal education (although they may encounter the subjective perspective in informal education). The typical example of classical probability would be a fair dice roll because it is equal… Let's take a look at a few examples of how to determine probability. Probability is a statistical concept that measures the likelihood of something happening. Probability isn’t just expressed using mathematical percentages. It’s equally likely you would get a 1, 2, 3, 4, 5, or 6. ). 1 - Classical Probability Formula Classical probability is used when each in a sample space is equally likely to occur. Learn more about this topic with the lesson that accompanies this quiz, titled Classical Probability: Definition, Approach & Examples. Finding the classical probability. Simple Probability. Choosing a card from a standard deck of cards gives you a 1/52 chance of getting a particular card, no matter what card you choose. Classical probability is the statistical concept that measures the likelihood (probability) of something happening. A die is thrown 1000 times with the following frequency for the outcomes 1, 2, 3, 4, 5 and 6 as given … For example,  the odds of rolling a 2 on a fair die are one out of 6, (1/6). Probability Quantifying the likelihood that something is going to happen. In a classic sense, it means that every statistical experiment will contain elements that are equally likely to happen (equal chances of occurrence of something). Here is a classic statement by de Moivre: Other Examples of classical Probability. With Chegg Study, you can get step-by-step solutions to your questions from an expert in the field. Formula for Classical Probability. Examples include flipping coins, drawing cards from a deck, guessing on a multiple choice test, selecting jellybeans from a bag, choosing people for a committee, and so on. P(A ∩ B) = P(A) x P(B) = 0.667 x 0.833 = 0.556. Classical (or theoretical) probability is the ration of the number of outcomes of an event to the total number of outcomes in the sample space. Examples: heads on a coin toss, is equal to the ratio of the number of "equipossibilies" (or equiprobable events) favourable to the event in question to the total number of relevant equipossibilities.' Many politics analysts use the tactics of probability to predict the outcome of the election’s … We'll use the following model to help calculate the probability of simple events. Use These Examples of Probability To Guide You Through Calculating the Probability of Simple Events. Flew and Priest (2002) 'The classical theory defines an event's probability as the proportion of alternatives, among all those possible in a given situation, that include the event in question. There might be a 15% chance of rain (and therefore, an 85% chance of it not raining). There is an equal probability that your toss will yield either head or tail. 2 A Quality Assurance inspector tests 200 circuit boards a day. Probability is simply the possibility of the happening of an event. We want to determine the probability that … The classic probability is that in which all possible cases of an event have the same probability of occurring. Event E is given by E = {(1,3),(2,2),(3,1)} How to Calculate Probabilities? When P(A) = 0, A is known to be an impossible event and when P(A) = 1, A is known to be a sure event. A green die has numbers {1, 3, 4, 6, 8, 9, 10}. According to the above definition, the coin toss event is an example of a classical probability, since the probability of the result being expensive or being a stamp is equal to 1/2. You’ll need something more complicated than classical probability theory to solve them. Basically here we are assigning the probability value of \(\frac{1}{2}\) for the occurrence of each event. Hence, the following are some examples of equally likely events when throwing a die: Now let us take a simple example to understand the axiomatic approach to probability. If 2% of In most types of probability, quantitative informationQuantitative AnalysisQuantitative analysis is the process of collecting and evaluating measurable and verifiable data such as revenues, market share, and wages in order to understand the behavior and performance of a business. Dividing the number of events by the number of possible events is very simplistic, and it isn’t suited to finding probabilities for a lot of situations. Empirical Probability is based on the number of times an event occurs as a proportion of a known number of trials. Non-Mathematical Probability Examples . The “1” is the number of times the event can happen (you winning), divided by the number of possible number combinations (about 292,000,000) tickets sold. CLICK HERE!

classical probability examples

Posted on December 19, 2020 by in Uncategorized

Example 1: The typical example of classical probability would be rolling of a fair dice because it is equally probable that top face of die will be any of the 6 numbers on the die: 1, 2, 3, 4, 5, or 6. 1. It seems especially well suited to those games of chance that by their very design create such circumstances — for example, the classical probability of a fair die landing with an even number showing up is 3/6. The idea of the classical approach is that, given a collection of k elements out of n (where 0≤k≤n), the probability of occ… Classical probability is used when each in a sample space is equally likely to occur. Post was not sent - check your email addresses! An everyday example of a priori probability is your chances of winning a numbers-based lottery. Classical probabilityis the statistical concept that measures the likelihood of something happening, but in a classic sense, it also means that every statistical experiment will contain elements that are equally likely to happen. Examples include flipping coins, drawing cards from a deck, guessing on a multiple choice test, selecting jellybeans from a bag, choosing people for a committee, and so on. Empirical and classical … First we have to find every possible outcome, and we are going to call this a “sample space”, in the case of rolling a dice we already know that we have 6 different outcomes, one for each face of the dice, so we can define the sample space like this: {1,2,3,4,5,6} probability mass function (pmf) p(x), organized in a probability table, and displayed via a corresponding probability histogram, as shown. So there are a total of 3 possible outcomes out of 36 equally likely outcomes, and so that's a probability of 1 in 12. In the era of data technology, quantitative analysis is considered the preferred approach to making informed decisions.is interpreted to determine the likelihood of something happening. Probability for Class 10 is an important topic for the students which explains all the basic concepts of this topic. This approach traces back to the field where probability was first sistematically employed, which is gambling (flipping coins, tossing dice and so forth). In fact, most “real life” things aren’t simple events like coins, cards, or dice. Learn how your comment data is processed. The odds of winning Powerball are 1/292,000,000). There are many other types of classical probability problems besides rolling dice. This Classical approach works really well and we have equally likely outcomes or well-defined equally likely outcomes. i.e., n(A) = 18 The hope for many retail stores is that you have positive associations with Christmas music. where, $P(A)$ means “probability of event A” (event $A$ is whatever event you are looking for, like winning the lottery, that is event of interest), $f$ is the frequency, or number of possible times the event could happen and $N$ is the number of times the event could happen. Classical (or theoretical) probability is the ration of the number of outcomes of an event to the total number of outcomes in the sample space. There are three types of probabilities as you have already mentioned in your question. Our first look at probability concerns classical probability theory. Politics. 1. Example 6: Two dice are rolled (see example 3 above for the sample space). Let’s size the difference between the frequency-based and classical approach with the following example. 1 - Classical Probability Formula Classical, Empirical, & Subjective Probability Empirical Probability Classical Probability observes the number of occurrences through experimentation calculates probability from a relative frequency distribution through the equation: Subjective Probability We know the number of Need to post a correction? View Classical Probability Example.pdf from ECMT 461 at Texas A&M University. In fact, most “real life” things aren’t simple events like coins, cards, or dice. Another example is rolling two dice. 2. The probability of all the events in a sample space adds up to 1. Your first 30 minutes with a Chegg tutor is free! N is the number of times the event could happen. On the contrary, if the probability of an event happening is 1, then it is 100% sure that the event will happen.

If the pitched softball knocks over all three bottles, the contestant wins. Guessing on a test. The term probability refers to the likelihood of an event occurring. Here are few example problems with solutions on probability, which helps you to learn probability calculation easily. The classical definition or interpretation of probability is identified with the works of Jacob Bernoulli and Pierre-Simon Laplace.As stated in Laplace's Théorie analytique des probabilités, . Classical probability definition: the probability of an event consisting of n out of m possible equally likely occurrences... | Meaning, pronunciation, translations and examples Comments? The classic approach will argue that the probability of "tails" in one flip is $1/2$ because there are only two possible outcomes and "tails" is one of them $\frac{m}{n}=\frac{1}{2}$. So, in classical probability you think of the space of the outcomes and try to find an abstract reason to assign the probability (we used mathematics logic to came up with the number of possibilities and the one of outcomes). It has been originated in 18th century which explains probability concerning games of chances such as throwing coin, dice, drawing cards etc. For example, natural events like weights, heights, and test scores need normal distribution probability charts to calculate probabilities. A classical harmonic oscillator with mass and spring constant has a total energy , dependent on its amplitude .We determine the probability density as the position varies between and , making use of its oscillation frequency (or period ).Thus we find the probability density function where representing the probability that the mass would be found in the infinitesial interval to . These examples include flipping coins, drawing cards from a deck, guessing on a multiple choice test, selecting jellybeans from a bag, and choosing people for a committee, etc. The formula for calculating the probability becomes much more complex as … Learn more about this topic with the lesson that accompanies this quiz, titled Classical Probability: Definition, Approach & Examples. Event E is given by E = {(1,3),(2,2),(3,1)} How to Calculate Probabilities? We could ask other questions, for example, is this a fair die? Classical Probability cannot be used: Subjective probability refers to probability that is based on experience or personal judgment. The probability of someone in this population favoring blue is the relative frequency 39/150 = 0.26 . For example, if you throw a die, then the probability of getting 1 is 1/6. We pick at random 150 people in this population, and 39 of the 150 favor blue. You might not even realize you are expressing probability, but you are. Classical Probability Examples Market research in a particular city indicated that during a week, 18% of all adults watch For example: The probability of a simple event happening is the number of times the event can happen, divided by the number of possible events. 3. Write out a 6 by 6 table of all 36 possible outcomes when the two are thrown. The “mathy” way of writing the formula is P(A) = f / N. P(A) means “probability of event A” (event A is whatever event you are looking for, like winning the lottery). Dividing the number of events by the number of possible events is very simplistic, and it isn’t suited to finding probabilities for a lot of situations. What is the probability of the coin landing on heads? Sorry, your blog cannot share posts by email. Example: The probability of rain tomorrow is 60% The Bayesian view: Probabilities are assigned based on your prior knowledge and your assumptions. It contains no … http://www.criticalthinkeracademy.com This video gives an introduction to the so-called "classical" interpretation of probability. Solutions will be gone over in class or posted later. Online Tables (z-table, chi-square, t-dist etc. Classical, Empirical, & Subjective Probability Empirical Probability Classical Probability observes the number of occurrences through experimentation calculates probability from a relative frequency distribution through the equation: Subjective Probability We know the number of It is often presupposed (usually tacitly) in textbook probability puzzles. For example, suppose we consider tossing a fair die. These examples include flipping coins, drawing cards from a deck, guessing on a multiple choice test, selecting jellybeans from a bag, and choosing people for a committee, etc. Probability is the chance or likelihood that an event will happen. The probability of an event occurring is the number in the event divided by the number in the sample space. This gives us the formula for classical probability. Example 6: Two dice are rolled (see example 3 above for the sample space). Example 3: In selecting bingo balls, each numbered ball has an equal chance of being chosen. There are many other examples of classical probability problems besides rolling dice. For example, suppose we consider tossing a fair die. of exhaustive cases = 2 ∴ Probability of obtaining head P(H) =1/2. Classical (sometimes called "A priori" or "Theoretical") This is the perspective on probability that most people first encounter in formal education (although they may encounter the subjective perspective in informal education). Examples: Throwing dice, experiments with decks of cards, random walk, and tossing coins. of cases favorable to the occurrence of head = 1 No. Let us define event E as the set of possible outcomes where the sum of the numbers on the faces of the two dice is equal to four. Audi (1999) The typical example of classical probability would be a fair dice roll because it is equally probable that you will land on an… Classical probability refers to a probability that is based on formal reasoning. 4. On the other hand, figuring out will it rain tomorrow or not isn’t something you can figure out with this basic type of probability. 2. That’s one possible outcome (there’s only one way to roll a 1!) Another example : what is the probability of tails when flipping a fair coin? There are many other examples of classical probability problems besides rolling dice. Classical Probability cannot be used: In connection with classical definition of probability, we may note the following points. Classical Probability: Example, Definition, and Uses in Life Classical Probability Examples. Axiomatic Probability Example. Classical probability theory on ℝ or ℝ k is mostly concerned with the limiting behaviour of the partial sum sequence (S n) n ⩾ 1.The most important and famous results are the (strong) law of large numbers (LLN), the central limit theorem (CLT) and the law of the iterated logarithmic (LIL) which, for real-valued random variables, may be summarized in the following way. It means that none of them is more or less likely to occur than other ones, hence they are said to be in a symmetrical position. To find the classical probability we are going to use the example of rolling a dice. Examples 1 Plot pdf and cdf of a binomial distribution with p = 0.2 and n = 10. —Paul J. Nahin, Professor Emeritus of Electrical Engineering, University of New Hampshire Classic Problems of Probability presents a lively account of the most intriguing aspects of statistics. Subjective probability. For a detailed example of using the formula, see: Probability of a Simple Event Happening. Thus, all the conditions of the classical definition are satisfied. Place a "2" in every cell for which R > G and determine P(R > G). This site uses Akismet to reduce spam. Classic probability . Therefore, the concept of classical probability is the simplest form of probability that has equal odds of something happening. 1-9 A red die has face numbers {2, 4, 7, 12, 5, 11}. Prior to this, dogs were a fairly neutral stimulus. Need help with a homework or test question? Note that we do not allow for all fiv. Classical Probability: The classical approach to probability is one of the oldest and simplest school of thought. According to the above definition, the coin toss event is an example of a classical probability, since the probability of the result being expensive or being a stamp is equal to 1/2. Check out these fun examples of probability in everyday situations. For example, when we toss a coin, either we get Head OR Tail, only two possible outcomes are possible (H, T). He asked her to draw a card from the 12 cards. The odds of rolling a 2 on a fair die are one out of 6, or 1/6. For example, the probability of a male Englishman being between five and six feet tall is judged simply from the empirically given distribution of heights in the population." Imagine you want to know the probability of the outcome of your tossed coin being “head”. You’ll need something more complicated than classical probability theory to solve them. The classic probability is that in which all possible cases of an event have the same probability of occurring. Selecting bingo balls. You can only use classical probability for very basic events, like dice rolls. Classical Probability is based on the assumption that the outcomes of an experiment are equally likely, for example, rolling a fair dice. 2. “f” is the frequency, or number of possible times the event could happen. That is, 0 ≤ P(A) ≤ 1. divided by the number of possible outcomes (1,2,3,4,5,6). EMPIRICAL OR STATISTICAL PROBABILITY EXAMPLE 3.3.10 A carnival game requires the contestant to throw a softball at a stack of three "bottles." To understand better the general definition of classical probability we are going to take the next example: there is a group of people which are listed by numbers between 1 and 10, and one of them are going to get a price, the decision will be make by picking a random number between 1 and 10 and the person with that number is going to be the winner. This lesson shows you how to compute for the probability of an event under the classical probability. Gambling problems are characterized by random experiments which have n possible outcomes, equally likely to occur. Subjective probability is the only type of probability that incorporates personal beliefs. Important Points (a) The probability of an event lies between 0 and 1, both inclusive. Classical probability is a simple form of probability that has equal odds of something happening. Each numbered ball has an equal chance of being chosen. Classical Probability examples. Opinion Poll Example: It is desired to know what the probability is that someone in a particular population favors blue over other colors. The Classical Model of Probability . The probability of a simple event happening is the number of times the event can happen, divided by the number of possible events (outcomes). Example 2: Another example of classical probability would be tossing an unbiased coin. They are speaking in mathematical probabilities. We will go over this concept in Examples 2 and 3. imaginable degree, area of Her favorable outcome is a king and there are 4 kings in Jonathan's hands. There are many other examples of classical probability problems besides rolling dice. Use the data to answer each of the following questions. Classical Probability Probabilities are assigned to individual events. These examples include flipping coins, drawing cards from a deck, guessing on a multiple choice test, selecting jellybeans from a bag, and choosing people for a committee, etc. Other Examples of classical Probability. Classical probability theory on ℝ or ℝ k is mostly concerned with the limiting behaviour of the partial sum sequence (S n) n ⩾ 1.The most important and famous results are the (strong) law of large numbers (LLN), the central limit theorem (CLT) and the law of the iterated logarithmic (LIL) which, for real-valued random variables, may be summarized in the following way. Similarly, the probability of getting all the numbers from 2,3,4,5 and 6, one at a time is 1/6. Based on how poorly the … No. The typical example of classical probability would be a fair dice roll because it is equal… The classic probability is that in which all possible cases of an event have the same probability of occurring. 1. A great book, one that I will certainly add to my personal library. On tossing a coin we say that the probability of occurrence of head and tail is \(\frac{1}{2}\) each. Classical Probability Event A result of an experiment Outcome A result of the experiment that cannot be broken down into smaller events 4 Sample Space The set of all possible outcomes Probability Event Occurs # of elements in Event / # Elements in Sample Space Example –flip two coins, find the probability of exactly 1 head.

Classical probability can be used for very basic events, like rolling a dice and tossing a coin, it can also be used when occurrence of all events is equally likely. The classical definition or interpretation of probability is identified with the works of Jacob Bernoulli and Pierre-Simon Laplace.As stated in Laplace's Théorie analytique des probabilités, . For example, natural events like weights, heights, and test scores need normal distribution probability charts to calculate probabilities. There are many other types of classical probability problems besides rolling dice. What is probability? Classical (sometimes called "A priori" or "Theoretical") This is the perspective on probability that most people first encounter in formal education (although they may encounter the subjective perspective in informal education). The typical example of classical probability would be a fair dice roll because it is equal… Let's take a look at a few examples of how to determine probability. Probability is a statistical concept that measures the likelihood of something happening. Probability isn’t just expressed using mathematical percentages. It’s equally likely you would get a 1, 2, 3, 4, 5, or 6. ). 1 - Classical Probability Formula Classical probability is used when each in a sample space is equally likely to occur. Learn more about this topic with the lesson that accompanies this quiz, titled Classical Probability: Definition, Approach & Examples. Finding the classical probability. Simple Probability. Choosing a card from a standard deck of cards gives you a 1/52 chance of getting a particular card, no matter what card you choose. Classical probability is the statistical concept that measures the likelihood (probability) of something happening. A die is thrown 1000 times with the following frequency for the outcomes 1, 2, 3, 4, 5 and 6 as given … For example,  the odds of rolling a 2 on a fair die are one out of 6, (1/6). Probability Quantifying the likelihood that something is going to happen. In a classic sense, it means that every statistical experiment will contain elements that are equally likely to happen (equal chances of occurrence of something). Here is a classic statement by de Moivre: Other Examples of classical Probability. With Chegg Study, you can get step-by-step solutions to your questions from an expert in the field. Formula for Classical Probability. Examples include flipping coins, drawing cards from a deck, guessing on a multiple choice test, selecting jellybeans from a bag, choosing people for a committee, and so on. P(A ∩ B) = P(A) x P(B) = 0.667 x 0.833 = 0.556. Classical (or theoretical) probability is the ration of the number of outcomes of an event to the total number of outcomes in the sample space. Examples: heads on a coin toss, is equal to the ratio of the number of "equipossibilies" (or equiprobable events) favourable to the event in question to the total number of relevant equipossibilities.' Many politics analysts use the tactics of probability to predict the outcome of the election’s … We'll use the following model to help calculate the probability of simple events. Use These Examples of Probability To Guide You Through Calculating the Probability of Simple Events. Flew and Priest (2002) 'The classical theory defines an event's probability as the proportion of alternatives, among all those possible in a given situation, that include the event in question. There might be a 15% chance of rain (and therefore, an 85% chance of it not raining). There is an equal probability that your toss will yield either head or tail. 2 A Quality Assurance inspector tests 200 circuit boards a day. Probability is simply the possibility of the happening of an event. We want to determine the probability that … The classic probability is that in which all possible cases of an event have the same probability of occurring. Event E is given by E = {(1,3),(2,2),(3,1)} How to Calculate Probabilities? When P(A) = 0, A is known to be an impossible event and when P(A) = 1, A is known to be a sure event. A green die has numbers {1, 3, 4, 6, 8, 9, 10}. According to the above definition, the coin toss event is an example of a classical probability, since the probability of the result being expensive or being a stamp is equal to 1/2. You’ll need something more complicated than classical probability theory to solve them. Basically here we are assigning the probability value of \(\frac{1}{2}\) for the occurrence of each event. Hence, the following are some examples of equally likely events when throwing a die: Now let us take a simple example to understand the axiomatic approach to probability. If 2% of In most types of probability, quantitative informationQuantitative AnalysisQuantitative analysis is the process of collecting and evaluating measurable and verifiable data such as revenues, market share, and wages in order to understand the behavior and performance of a business. Dividing the number of events by the number of possible events is very simplistic, and it isn’t suited to finding probabilities for a lot of situations. Empirical Probability is based on the number of times an event occurs as a proportion of a known number of trials. Non-Mathematical Probability Examples . The “1” is the number of times the event can happen (you winning), divided by the number of possible number combinations (about 292,000,000) tickets sold. CLICK HERE!
