Matching pairs (Posted on 2002-04-23) Difficulty: 3 of 5
A standard deck of 52 cards is shuffled, and we take cards from its top in pairs.

If both are of a red suit, I take both cards. If both are black - you take them. If they are different colors - we put them in the discard pile.

If at the end of the deck you have more cards than I, I will pay you a dollar.

If I have more cards, or if we have the same amount of cards, I pay you nothing.

What is a fair "admission price" to play this game?
