Using problems and examples from Texas Holdem, rather than the standard balls and urns, this is a fun and engaging textbook for an introductory course in probability. The book covers all of the fundamentals, including the axioms of probability, permutations and combinations, conditional probability, independence, Bayes#xE2;#xAC;" rule, discrete and continuous random variables, simulation, expected value, correlation, conditional expectation, laws of large numbers, the central limit theorem, Brownian motion, and Markov chains. Supplementary R code is available for implementing topics in computational probability relating to Texas Holdem.
