Mathematical expectation or expected value represents the long-term average numerical outcome to an experiment performed a large number of times. Routinely used in the physical sciences, business, and economics, mathematical expectation has also been used to calculate strategies in games of chance and even to justify the belief in God.

In an easily accessible presentation, this book explores these puzzling and entertaining mysteries-- Provided by publisher.
