Craps is fundamentally a game of probability. When throwing two six-sided dice, there are 36 possible outcomes. Each combination from 2 through 12 has a specific probability of occurring. The number 7 is the most probable outcome with six different combinations: 1-6, 2-5, 3-4, 4-3, 5-2, and 6-1. Understanding these probabilities is essential for evaluating bet value and long-term expectations.
The probability of rolling a 7 is 6/36 or approximately 16.67%. Other numbers have lower probabilities. For example, rolling an 11 occurs in only 2/36 outcomes, while rolling a 2 or 12 happens in just 1/36 outcomes each. These mathematical foundations determine which bets offer better odds to the player.
