Nine quintillion...put THAT in your pipe and smoke it!

From the Victor Neiderhoffer's Daily Speculations site:

The odds of one person's filling out a perfect bracket for the NCAA basketball tournament, i.e., the odds of picking every single game winner correctly is nine quintillion to one.
Another way to view this is that if every person on the planet were to randomly fill out one million sheets the chances would be one in 1000 that a perfect sheet would be found.
The odds of picking the five numbers in the Powerball lottery are one in 3,563,609 but to pick all five numbers and the powerball are one in 146,107,962.
