    1. The problem statement, all variables and given/known data
    2. Relevant equations

    I'm not sure, to be honest.

    3. The attempt at a solution

    I was helping out my roommate with his probability homework, and this question came up. I'm not sure how to answer it. How is this done?

    Ahaha... I did not know there was a Wikipedia article on what seemed to me to be just an unusually difficult homework problem. Thanks!
