Alright, i got assigned this, and have no idea how to begin. I'm not looking for an answer (wait, yes I am, but don't expect one). Could someone maybe give me a little guidence?

Let Yn be the sum of n independent rolls of a fair die. Find the probability that Yn is a multiple of 13, as n goes to infinity.

This is what I have, nothing more than a mathematical writing of the problem

lim P{Yn is a multiple of 13}
n-> inf.

Help me?
