The probability of dice combinations determine the odds of normally no possible long-term winning strategy in craps. Overall, given the true odds of this bet, and the weighted average paid odds.

One way is to ask how many rolls it will take to have a better than even chance of a seven out. The other is to ask how many rolls, on average, a Craps hand will.

This month I'll address the latter question, which is the easier of the two questions. In this case I would do a second trial. Think of this as follows. How long is a Craps hand? Note that on the first roll I could get a failure and the number of trials would be 1. One way is to ask how many rolls it will take to have a better than even chance of a seven out. Don Catlin is a retired professor of mathematics and statistics from the University of Massachusetts. What is the average number of rolls that a Craps hand will last? This fraction is approximately 3. Although this is conceptually the right idea, we cannot possibly carry out such a calculation. In other words, n is what we called a random variable back in the July article. This is the same as asking for the expected number of rolls in a Craps hand see the discussion of the exp function in my July article Right question, Right Answer, Hopefully. What can we do? Gaming News. Here we go. Suppose that p represents the probability of success and q represents the probability of failure at each trial. See you then. Suppose that the trial consists of rolling a single die. Suppose that I have a series of independent trials such that each trial results in one of two outcomes; I'll call them success and failure. First let us calculate the expected number of rolls for a Pass Line decision. An infinite sum, no less. In other words, if we did this die rolling experiment over and over many times, each time keeping track of how many rolls it took until the 5 appeared, then took the average of all of these numbers, the result would be a number near 6. To do this we will calculate the expected number of rolls for each of the possible things that will lead to a Pass Line decision and weight each one by the probability that it occurs. If h represents one particular Craps hand in this set, we could denote by n h the number of rolls that particular Craps hand lasts. How many rolls can I expect on average until the five occurs? Well now, we have our problem solved. In other words, how many trials can I expect on average until a failure occurs? I want to stop for a moment and look at a more general question and one that will be central to our solution of the Craps problem. This article is provided by the Frank Scoblete Network. Weekly Newsletter. YOU are responsible for determining if it is legal for YOU to play any particular games or place any particular wager. Here's the plan. So we need to calculate q , the probability that a seven out occurs given that a Pass Line decision is reached. How Long is a Roll? Kaplan is the network's managing editor. Remember this happens with frequency p. According to 4 above, interpreting a settlement as failure, it will take an average of 4 rolls to settle the bet. Where Are Those Straight Flushes? On the other hand, I could have success on the first trial and this happens with frequency p. To be precise, the sample space here consists of all possible Craps hands, an infinite set. What is the expected number of trials in this situation? Articles in this Series How Long is a Roll?{/INSERTKEYS}{/PARAGRAPH} Gaming Gurus. Warning: You must ensure you meet all age and other regulatory requirements before entering a Casino or placing a wager. That is to say, how many rolls does it take until the shooter sevens out? When a Pass Line decision is reached, that is considered as one game. In terms of relation 4 , A Natural, Craps, or a Point made is a success; a seven out is a failure. Here's how. Okay, we're ready to roll. All you have to do is add up all of the probabilities for a seven out on each of the six possible points. Let me give you a simple example. Next we want to determine the number of Pass Line decisions per seven out. Newsletter Signup. Notice, however, that because of the independence of the trials, when I face this second trial the number of trials until failure I expect from this point is the same as the number I faced at the first trial, namely e. {PARAGRAPH}{INSERTKEYS}In this article and next month's article I want to look at a question that gets kicked around the Craps table now and then. The complete set of calculations is given in the table below. Melissa A. Remember independence means that no set of outcomes has any influence on any other set of outcomes. There are a couple of ways to look at this question and they are distinctly different. The other is to ask how many rolls, on average, a Craps hand will last. His original research area was in Stochastic Estimation applied to submarine navigation problems but has spent the last several years doing gaming analysis for gaming developers and writing about gaming. In other words, if you played many, many Crap games each decision is a game , kept track of the total number of rolls, and divided the number of rolls by the number of games, the result would be approximately 3. Success will mean that a non-five is rolled and failure will be the occurrence of the five. To calculate exp n one would ostensibly have to find the probability prob h of each craps hand, form the product prob h n h for each hand h , and add up all of these numbers for each and every hand h. This would happen with frequency q. Suppose we could figure out the average number of rolls per Pass Line decision and also the average number of Pass Line decisions per seven out. We want to keep playing and add the total number of games played until a seven out is reached. If you would like to use this article on your website, please contact Casino City Press , the exclusive web syndication outlet for the Frank Scoblete Network. Well, not quite. Getting back to the general question, let us let e represent the expected number of trials until failure. Fine, but how do we get hold of these numbers? So, on average, you can expect to hold the dice about eight and a half rolls when playing Craps. The number we want, the average number of rolls per seven out, would simply be the product of these two numbers. We bet the Pass Line at Craps over and over. The answers to these two questions are quite different and Craps players sometimes get them confused with each other. Next month we'll look at the harder problem of determining how many rolls it takes to have an even chance of losing the dice. To contact Frank, please e-mail him at fscobe optonline. I keep repeating the trials until I get a failure. There are hundreds of jurisdictions in the world with Internet access and hundreds of different games and gambling opportunities available on the Internet.
