1) Assuming the probability of guessing the winner in any NCAA basketball tournament game is 0.5 (that is an even toss-up), what is the probability of picking the winner in all the games?

Would I use (0.5/number of games)

2) What dollar value would be required as a prize for guessing all the winners for your expected value of guessing to be $1?
