America starts filling out March Madness brackets

A math professor at University of Cincinnati is bringing March Madness into the classroom.

Earlier this year, Mike Magazine introduced his Bracketology class to the business school at the home of the Bearcats. He's teaching business students about the math involved in analyzing teams and filling out their brackets.

The 68-team field came out Sunday, meaning Monday was the unofficial Bracket Day across America - when fans and non-fans alike start making their picks, choosing winners of the 67 games, with hopes of cashing in on the $10 and $20 investments they're making in office pools across America.

The biggest lesson learned in his class, Magazine says, is that math leads us toward lots of correct decisions. Still, that's no guarantee that outcomes always come out the way we plan.
