# Math Help - Rolling n dice

1. ## Rolling n dice

(a) How many different outcomes are there from rolling n identical dice?
(b) How many of these sequences contain at least one 6?

I got $6^n$ for part(a) but I'm very muddled over the 2nd part of this question...

I got $6^n$ for part(a) ...CORRECT
b) $6^n -5^n$. WHY?

3. Because $5^n$ contains no 6's at all.

Thanks!
