Why is 11 called yo in craps

You win if a 7 or 11 roll, or lose if 2, 3, or 12 roll (known as “craps”). Any other number that rolls becomes the “point” and the point must roll again before a 7 to win.

With a “horn, high yo,” $1 is put in 2, 3 and 12, and $2 goes on 11. A “horn, high 12” chance puts the $2 on 12 and $1 on the other numbers. A “horn, high aces” chance means the $2 goes on the 2, with $1 on the other numbers. There’s probably a name for the chance where $2 goes on the 3, but we have no idea what it is.

Every time you add a die, the number of total outcomes is multiplied by 6. If you roll a pair of dice, for example, the number of total outcomes is 6² = 6 × 6 = 36, meaning every roll of the dice has a total of 36 possible outcomes. Therefore, the probability of rolling an 11 with two dice is 1/18.

Crap 12 One-roll chance. If 12 rolls, the chance wins. Any other number loses.
