LOUISVILLE, Ky. (WDRB) -- Think the odds are long for winning the Powerball? That's nothing compared to your chances of having a perfect bracket for the NCAA tournament.

Depaul University mathematics professor Jeff Bergen says the odds of making all of the right picks are less than one in 9.2 quintillion.

A quintillion is about a billion billion.

Bergen says it would be easier to win the Mega Millions lottery two times in a row -- or for the next 16 World Series to be won by the Chicago Cubs and White Sox.

The tournament begins two weeks from Tuesday.
