Cheat Your Friends At A Fair Coin Toss! (2010x37)

Air date: Sep 15, 2010

The Setup: using a totally fair quarter, you and your friend will place bets on which sequence of coin tosses are most likely to come first... while it looks totally fair, you'll have up to a 7 to 1 advantage over them! The Scam: This is an old math problem called "Penney's Game". In this game, each player chooses a 3-digit sequence of coin flips... a coin is flipped over and over again, and whomever's sequence of heads and tails comes first, wins. in other words, player 1 may choose HTH (heads, tails, heads) as his sequence, while player 2 would choose HHT. when the coin is flipped, the results may be: TTHTTHHT, in which case, player 2 would win.
