How many possibilities/picks are there in an NCAA pool tournament bracket?

Question

What are the odds of getting a perfect bracket?

Answer 1

there are roughly 2^63 different possibilities. That is indeed 2 to the 63rd power. It comes out to be roughly 9 quintillion. That would be that if every person, man, women, and child, on the planet filled out ONE MILLION brackets each, there would still be only a 1 in about 1000 chance that someone had the totally correct bracket

Answer 2

very slim. But If you have faith in your NCAA picks in ur pool then you just might have it.

Each year My picks NEVER change. So Ever year my pool is ALWAYS perfect. I only love one team so each year its perfect for me at least.
