    Undergrad Two fair dice are thrown, with the scores (X1, X2).

    Need help with this problem, please! 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.
