N.C.A.A. Basketball Tournament Each year, 64 college basketball teams compete in the N.C.A.A. tournament. Sandbox.com recently offered a prize of $10 million to anyone who could correctly pick the winner in each of the tournament games. The president of that company also promised that, in addition to the cash prize, he would eat a bucket of worms. Yuck.

b. If someone makes random guesses for each game of the tournament, find the probability of picking the winner in each game.
