Do you have your 2017 NCAA men鈥檚 basketball tournament bracket filled out for the annual office pool? Just remember: You don鈥檛 need a perfect bracket, just one that tops those of your workmates.
So what are the odds of filling out a perfect NCAA tournament bracket, picking all 63 games correctly? According to University of Colorado Boulder Professor Mark Ablowitz of the聽Department of Applied Mathematics, they are astonishing.
Try about 1 in 9.2 quintillion (or about 1 in 9,223,000,000,000,000,000)聽for someone picking winners of each game randomly, like a coin flip, said Ablowitz. But anyone with some knowledge of college basketball can up their odds a bit, he notes. A 16-seed has聽 never upset a 1-seed in any of the four regions, for example,聽since the field expanded to 64 teams in 1985.
鈥淭hese aren鈥檛 just numbers,鈥� said Ablowitz, who specializes in the mathematics of waves such as lasers and water waves. 鈥淭he real essence here is the issue of the behavior of large numbers. When numbers get exponentially larger and larger, things get out of hand very, very quickly.鈥�
How good (or bad) are the odds? In 2014, billionaire businessman Warren Buffet offered up a $1-billion prize for anyone on the planet who could fill out a perfect bracket, a prize that went unclaimed. This year he is offering $1 million a year for life to any of his Berkshire Hathaway employees who pick the Sweet 16 field correctly.
But even picking every team down to the Sweet 16 is a tough task, says Ablowitz鈥攖he odds of randomly guessing all of the winners here is about 1 in 282 trillion. 鈥淚t鈥檚 still super-duper large, so no one is likely to get this one either,鈥� he acknowledged.
Some have calculated the odds of picking all 63 NCAA tournament games correctly would be about the same as shooting four hole-in-ones in a single round of golf, winning three consecutive Powerball lotteries, or the Denver Broncos winning the next 13 consecutive Super Bowls.
Suppose one waits until the Sweet 16 is finalized before picking the winner of the championship game. The odds are better but still only 1 in 32,767, said Ablowitz, who did all the arithmetic on his pocket calculator. And to pick the winner of the final eight teams, the odds are 1 in just 127, if selected randomly.
鈥淚鈥檓 not a basketball maven,鈥� says Ablowitz, a faculty member in the聽聽鈥淏ut if I wanted to improve my personal odds, I might look at 10 high-profile sports websites that gave the odds for each game, then averaged those. Using 10 sources rather than one source smooths the numbers out a little, so you wouldn鈥檛 be putting all of your money in one basket.鈥�
The final NCAA brackets will be announced on 鈥淪election Sunday鈥� March 12.
