Picking the Perfect NCAA Bracket

Thursday, March 23rd, 2006

Carl Bialik, the Numbers Guys, explains the astronomical odds of Picking the Perfect NCAA Bracket:

Filling out a perfect bracket means predicting the outcome of 63 games. If each game were a true toss-up, that would mean your chance of perfection is a mere one in two to the 63rd power, or one in nine million trillion (yes, million trillion — there are no tidy terms for numbers this large). Put another way, you are about 60 billion times more likely to win the multistate Powerball lottery.

Of course, you can do better than just flipping a coin for each game. Some teams are better than others. I spoke with a half-dozen statisticians and mathematicians to get their best guesses about how well an informed picker could theoretically do. The most generous estimate for the chance of a perfect bracket: about one in 150 million.
