The Mathematics Behind the Dice
Craps is one of the most mathematically fascinating casino games, built entirely on probability and the outcomes of two standard six-sided dice. With 36 possible combinations (6 × 6), understanding the frequency of each result is fundamental to grasping the game's betting structure and odds. The number 7 appears most frequently with six combinations (1-6, 2-5, 3-4, 4-3, 5-2, 6-1), occurring once every 3.6 rolls on average. This high frequency of 7 is the cornerstone of craps strategy, as many bets win or lose depending on whether 7 appears.
