Need help with this problem, please!(adsbygoogle = window.adsbygoogle || []).push({});

Two standard, fair dice are thrown, and the scores (X1, X2) are recorded. Find the expected value of each of the following variables:

(a) Y = X1 + X2

(b) Z = X1*X2

I don't even understand what it's asking! :( Any help is appreciated.
