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!

Perfect Bracket Odds:
There are 9,223,372,036,854,775,808 possible brackets.

That's the number nine follow by eighteen zeros.

That's over 9.2 quintillion. (My note: See - there are tidy terms for numbers this big. :)

Some examples of just how big this number is:

If everyone on the planet each randomly filled out a bracket, the odds would be over ONE BILLION to 1 against any person having a perfect bracket.

If one bracket per second was filled out, it would take 292 TRILLION years to fill out all possible brackets (that's 20 times longer than the universe has existed).

If all the people on earth filled out one bracket per second, it would take over 43 years to fill out every possible bracket.

If all possible brackets were stacked on top of each other (on standard paper), the pile would reach from the moon and back over 1.1 million times.

All possible brackets (on standard paper) would weigh 90,000 times more than every man, women, and child on earth combined.

Even if a person had a 90% chance of winning each game he picked, his odds would still be 763 to 1 against picking a perfect bracket.

68 vs. 64 teams:

The calculations above assume a 64 team bracket – if expanded to consider 68 teams, multiple the figures by SIXTEEN.
