Like many Americans, you probably filled out a March Madness bracket recently. And like many Americans, your bracket will almost certainly–almost very certainly–suck.

That’s to suggest that it won’t accurately predict the outcome of every single game, as DePaul University math professor Jeff Bergen demonstrates in this video. In fact, your chances of guessing at every match up and getting every team right is in the quintillions (18 zeroes). So, yeah, good luck with that.

But wait! You’re not guessing. What if you know some stuff about basketball? Well, you’ll still fail, probably. One in 128 billion odds there.

So maybe just play the lottery instead.
