What are the odds of rolling a 7 at a craps table?

Answer 1

1 in 6 The way you calculate this is as follows: There are 36 possible combinations you can get with two dice. Six of those combinations add up to 7 and 30 of those combinations add up to either 6, 5, 4, 3, or 2. Therefore, there are 30 ways you can roll a number other than seven and six ways you can roll a seven. If you want a seven to come out, there are 30 ways to lose and 6 ways to win. This translates into odds of 30 to 6 or 5 to 1. The difference between this and the above answer is the way odds are stated. They can be stated either using "in" or "to." You can say the odds are either 6 ways to win "in" 36 possible combinations or you can say there are 30 ways to lose "to" 6 ways to win. When these are reduced, they become 1 way to win "in" 6 ways to lose and 5 ways to lose "to" 1 way to win. Thus, you get "1 in 6" which is equivalent to "5 to 1".
