Peter and Mary take turns throwing one dart at the dartboard. Peter hits the bullseye with probability p and Mary hits the bullseye with probability r. Whoever hits the bullseye first wins. Suppose Peter throws the first dart and let y denote the number of darts thrown in the game. Find E[Y]. (Your answer in the case p = r should be familiar to you)
