Homework Statement
20 dice are rolled what's the probability that the sum will be divisible by 6?
Homework Equations
Law of total probability
The Attempt at a Solution
The possibilities are between 20x1 and 20x6:
24,30,36,42,48,54,60,66,72,78,84,90,96,102,108,114,120
In the beginning, trying to find out how many ways there are to get 24 from 20 dice makes me feel as though I can't possibly be expected to do it for all 17 totals. I have no idea how to do this
