Card games have long been a rich source of combinatorial exercises. Indeed, determining the probabilities of obtaining various hands in poker, and often in bridge, has been standard fare for elementary texts in both probability and combinatorics. Examples involving the game of cribbage, however, seem rare. This omission is especially surprising when one considers that cribbage hands offer excellent applications of combinatorial reasoning.
