Hi, can you help me with this problem, please?

I have tried but I am not sure what to do exactly...

Yn - sum of n independent rolls of a fair die.

Find lim P{Yn is a multiple of 13), n->inf

How can I define the appropriat Markov chain?

I know that after defining it I can use the limiting probability

If you can help me with this will be greatly appreciated.

Thank you!
