Problem:
Given two six sided dice compute the probability of rolling two 11's in a row.

You can put this solution on YOUR website!
There are two ways of getting an 11 with 2 dice, (5,6) and (6,5).
There are 6*6=36 possible sums with two 6 dice.
So the probability of getting an 11 with two dies is 2/36=1/18.
Because you're finding the probability of two succesive rolls, you multiply the probability of getting the first 11 * the probabilty of getting the second 11.
P(11 and 11)=(1/18)(1/18)=1/324=.0031
Happy Calculating!!!
