Friday Puzzler -- Chess Board 3 of 3

Well, not actually a chess board, since that is too small. Let's use a room with a floor painted in a chessboard pattern with 1" squares, as an approximation of an infinite chess board.

If you throw a coin, with a diameter of 1/2", on the floor, what is the probability that it will be touching two colors?
