In Craps, winning or losing depends on a variety of different possible outcomes on any roll of the two dice. The two dice can produce many different number combinations; some can be made several ways, others only one way. For example, two dice can roll the number 6 as follows: 5/1, 4/2, 3/3, 2/4 and 1/5. But the number 2 can only be rolled one way: 1/1.
