Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the dice has the numbers 1 through 6 on it.
in order to get to 11 or greater in 2 turns, he has to roll:

5 then 6 or 6 then 5 or 6 then 6.

the probability of any one number coming up is 1/6.

the probability of getting a 5 then a 6 is equal to 1/6 * 1/6 = 1/36.
the probability of getting a 6 then a 5 is equal to 1/6 * 1/6 = 1/36.
the probability of getting a 6 then a 6 is equal to 1/6 * 1/6 = 1/36.

the probability of getting a 5 then a 6, or a 6 then a 5, or a 6 then a 6, is equal to 1/36 + 1/36 + 1/36 = 3/36 = 1/12.
