# Using 2 6-sided dice what is the probability of rolling a sum that is a multiple of 3

Let (a,b) denote a possible outcome of rolling the two die, with a the number on the top of the first die and b Note that each of a and b can be any of the integers from 1 through 6. (2,1), (2, 2), (2, 3), (2,4), (2,5), (2, 6) Because there are 36 possibilities in all, and the sum of their probabilities must equal 1, each singleton.
