The Friday File: There is a billion dollar prize for correctly predicting all 63 games in the NCAA College basketball tournament. Assuming you can guess the winner 70% of the time, which has never been accomplished, your chance of winning is one in ten billion (1/10,000,000,000). Lowering your chances of prediction to 60% which is positively superhuman, your chance of winning falls to one in hundred trillion (1/100,000,000,000,000)! Good luck.
