It seems like everyone is filling out a bracket this week. So, what are the odds of picking a perfect NCAA bracket? A mathematics professor at DePaul University, calculates that if you “randomly” fill out your bracket, you've got about a one in 9.2 quintillion chance of getting them all correct. But, If you really know college basketball, your odds are a lot better at around one in 128 billion. That'd be like winning the Mega Millions lottery twice in a row, buying only one ticket each time. Bottom-line, skip the sobbing and gnashing of teeth when your hopes for a “perfect bracket” fall apart. The chances were never in your favor.
