In order to win a particular board game, a player must roll, with two dice, the exact number of spaces remaining to reach the end of the board. Suppose a player is two spaces from the end of the boar. Show the probabilkity distribution for the number of rolls required to win, up to ten rolls.

Hello icy,

The probability of success in repeated trials can be calculated by using the Bernoulli equation

P = n!/k!(n-k)! x p^k x q^n-k
P prob success ,n = number of trials,k = number of successes
p= prob single trial success, q = prob failure single trial, n-k number of failures
