Re: [math-fun] An illegal California lottery game

I have an indistinct memory that the reason the challenge to this game was successful was that one's ability to calculate a 'better' play amongst possible > presented options made the game into a "game of skill," and not a "lottery."

Both the lottery and keno are driven by the same thing, the hypergeometric distribution. It's also known as the Urn Problem. http://mathworld.wolfram.com/HypergeometricDistribution.html --Ed
