Spiked Math: MPF - Betting on the Next Card
It's Math Puzzle Friday! Yay!
We gave this problem to the students at Math Night on Wednesday. It appears in Peter Winkler's book Mathematical Puzzles: A connoisseur's Collection (on page 67) and is stated as follows:
See if you can solve it.
If you don't know where to start, try to solve it for a deck of 4 cards (2 black/2 red). What about 6 cards (3 black/3 red)?
Problem 2: What's the maximum amount he can assure himself of winning for a deck of 2n cards (with n black and n red)?
