NCAA Bracket Prediction Probability

Jeff Beren, a mathematics professor, explains the complexity of predicting a perfect NCAA tournament bracket. He starts with a simple four-team example, showing there are eight possible outcomes. For the NCAA tournament, with 64 teams, there are over 9 quintillion possible outcomes. Even with basketball knowledge, the odds of a perfect bracket are slim, at about one in 128 billion. This highlights the challenge and improbability of achieving a perfect bracket.
