Consider the simplest form of craps. In this game, we roll a pair of dice. If we roll a 7 or an 11 on the first throw, we win right away,. If we roll a 2 or a 3 or a 12, we lose right away. Any other total (that is, 4, 5, 6, 8, 9, or 10) gives us a second chance. In this part of the game, we keep rolling the dice until we get either a 7 or the total rolled on the first throw. If we simulation experiment to determine what percentage of the time we win.
