The faces of an octahedral die are labeled with digits 1 through 8. What is the probability, expressed as a common fraction, of rolling a sum of 15 with a pair of such octahedral dice?

There are 64 possible combinations of rolls: 8 x 8 = 64

But there are only two ways to roll a 15: 7,8 and 8,7

So the likelihood of rolling a 15 is 2 out of 64: 2/64 reduces to **1/32**
