Okay, we caught your attention. Is it possible to pick a perfect bracket for the NCAA men’s basketball March Madness championship tournament? According to Jeffrey Bergen, professor of mathematical sciences, the odds are not in your favor. “It would be more likely for the next 16 World Series to be won by the Chicago Cubs and the Chicago White Sox than it would be to pick a perfect bracket by guessing,” Bergen says. While knowledge of teams, players and coaches can certainly help your chances, the odds are still staggering slim. “With additional knowledge of basketball and the history of the tournament–such as knowing that a one seed had never lost to a 16 seed in the men’s tournament–the odds of picking a perfect bracket would be approximately one in 128 billion.” Without that knowledge? You’re looking at odds of less than one in 9.2 quintillion. Follow Bergen’s calculations in the video above.
