With an emphasis on mathematical thinking and problem solving, this text shows how discrete probability, statistics, and elementary discrete mathematics are used in games, sports, and gambling situations. It draws on numerous examples, questions, and problems to explain the application of mathematical theory to various real-life games. The text covers permutations in the two-deck matching game, introduces graphs to find matches when looking at extensions of the five-card trick, and studies lexicographic orderings and ideas of encoding for card tricks. It also explores linear equations and weighted equations in the section on the NFL passer rating formula.
