NEW YORK CITY, New York (AP) -- So, about that billion dollars.
Warren Buffett looks at the offer of $1 billion to anyone who fills out a perfect NCAA tournament bracket as nothing more than a matter of having the numbers in his favor.
Mathematicians say he's right, though that's not stopping them from building a cottage industry by teaching bracket-fillers how to make the impossible seem possible.
About a half-dozen colleges are offering special seminars and classes to teach people the ins and outs of the numbers that will, inevitably, work against them.
And there's one website - takebuffettsbillion.com - that sends a statistician-crunched bracket to anyone who signs up, with the promise that all those in on the gig will split the money if one of those brackets is the winner.
