Question 25
Mary and Noah play a fair coin-tossing game of at most seven rounds: Mary wins each head and Noah wins each tail. The first to four wins receives 10000 cents. Play is interrupted after three rounds, with Mary leading 2–1. If the prize is divided according to their probabilities of eventually winning, how many cents should Noah receive? Source clarification: the name “Ron” appears once in place of Noah; it refers to the same second player.
