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!
