Craps is a dice game where two dice are rolled and the sum of the dice one way to roll a sum of 2 (snake eyes or a 1 on both dice), so the probability of getting.

If you're trying to find the probability of losing the game, then it is the number of losses divided by the total number of games.{/INSERTKEYS}{/PARAGRAPH} We are then going to record the result of the first roll as "Win", "Lose", or "Point" in the table where it says "Result of first roll". This is a game that is most fun when it is simulated using actual dice. If you have rolled a point, continue to roll the die until you roll either that point or a 7, but do not record the value of each of those rolls. Eventually, you are going to either re-roll that point and win or roll a 7 and lose. Well, after all, the casinos want to make money, don't they? Count how many times you won and lost for the overall results and write that as a fraction over the total. So, if you're looking for the probability of rolling a 6, then it is the number of 6's over the total number of rolls. You should have lost a few more games than you won. But, becasue you could theoretically go on forever, finding the probabilities involve an infinite geometric series. Some of the probabilities are easy to find. Record them in the table below and compare them with the theoretical probabilities found by adding the theoretical probabilities as mentioned in the last paragraph or that we found earlier in this document. In this kind of simulation, you conduct an experiment and ultimately find the number of successes divided by the number of trials to find the relative frequency or the empirical probability. Here's how the simulation works. Roll a pair of dice and record the sum in the table where it says "Sum on first roll". They should get closer as you simulate more crap games law of large numbers. Are the observed probabilities close to the theoretical probabilities? If the sum is a 2, 3, 7, 11, or 12, go ahead and copy the first roll results into the overall results column and move on to the next game. What we're really interested in finding is the final outcomes of the game; that is, the probabilities of winning or losing the whole game. Record it in the table below as a fraction over the total number of rolls and compare it to the theoretical probabilities we found earlier. {PARAGRAPH}{INSERTKEYS}Craps is a dice game where two dice are rolled and the sum of the dice determines the outcome. Video : Use Real Player to listen to the instructions and watch several games to make sure you understand the game. Then you have to add all those probabilities up and that involves an infinite geometric series. You may wish to abbreviate the results as "W", "L", or "P". We can find the probability of winning, losing, or obtaining a point on the first roll of the game by adding up the probabilities for the sums that go with winning, losing, or getting a point. If you played the game right, this can also be found by adding the probabilities of getting a win 7 or 11 , lose 2, 3, or 12 , or point all else together. Now, in actual practice, it doesn't. As an example, consider the case when the point is a 9 that is shown in the tree diagram to the right. After you have played several games I recommend 36 since there are 36 different outcomes possible and it makes the probabilities nicer , it's time to sit back and look at what you have gathered. But it doesn't stop there, it keeps going, and going, and going. Did your results come out close to the theoretical results found using infinite geometric series or absorbing markov chains? Success is defined as whatever you're trying to find the probability of. So far, we haven't found anything that we couldn't find through simple probabilities and it was much quicker and more accurate exact instead of an approximation. The probabilities of obtaining any of the first roll sums can be found fairly easily and are shown in the table below. Once you have rolled your point or a 7, then record either "Win" or "Lose" in the table for the overall results. That might not be difficult for you, but since the prerequisite for the applied statistics course is just intermediate algebra, most of the students have never seen an infinite geometric series. This is a simulation used to find probabilities. Now add the number of times you got a win, lose, or point on the first roll of the dice and write that as a fraction. You're probably thinking to yourself that this has been pointless. The main problem with game of craps is that it can theoretically go on forever when a point is obtained on the first roll. Go through and count how many times each sum appeared as the first roll of the dice. Sure, it would be possible and quicker to simulate it using a computer, but it wouldn't be nearly as fun.
