Question: (Suggested by Sam Kaufmann, Indiana University MBA, who runs Harrah's Lake Tahoe Casino.) A high roller has come to the casino to play 300 games of craps. For each game of craps played there is a 0.493 probability that the high roller will win $1 and a 0.507 probability that the high roller will lose $1. After 300 games of craps, what is the probability that the casino will be behind more than $10?
