Hey verasi.

If you have two dice, then the probability of getting a sum of 6 is given by the combinations (1,5), (5,1), (2,4), (4,2) and (3,3). They all have a probability of 1/36 which means P(Sum = 6) = 5/36 and the P(Sum != 6) = 31/36

The question I have to ask before I continue, is a "second" roll another pair of rolls or is it the second part of the pair for the first pair of rolls?
