    [SOLVED] am i right?

    Question:

    We roll two dice. If the numbers are different we pay $3. If the numbers are the same we receive as many dollars as the product of the numbers shown on the die. For example, if we roll the number 5 and 5, we receive $25. Find the expected value of this game.


    I'm almost positive that I've worked this problem correctly and I came up with

    + 1/36

    Could someone confirm (or deny) this please.
