Penney Ante is a coin game devised in 1969 by a mathematician called Walter Penney. In it, two players predict three coin tosses. The prediction that appears first in a run of coin tosses wins. This should be a fair game. However, if Player 2 makes his prediction after Player 1, he can use mathematics and probability to increase his chances of winning. On Wednesday 9th of September 2009 (09-09-09) UK magician Derren Brown predicted the national lottery numbers on live TV. The following Friday he explained how he did it. This included a demonstration of the Penney Ante. For further reading see www.combinatorics.org
