The odds of you filling out a perfect bracket this year are a staggering 1 in 9.2 quintillion. That's a nine with 18 zeroes or 9,223,372,036,854,775,808 if you're not into the whole rounding thing.

How big is that?

• That's one billion, 9.2 billion times.

• It's 500,000 times more than our $17 trillion national debt.

• You'd have a better chance of hitting four holes-in-one in a single round of golf.

The 1 in 9.2 quintillion number is straight mathematics. It figures out how many possible ways the 63 game results on your bracket could be filled out. (Two to the sixty-third power.)
