Classical Probability The correspondence between Pascal and Fermat is the origin of the mathematical study of probability. The method they developed is now called the classical approach to computing probabilities. The method:Suppose a game has n equally likely outcomes,of which m outcomes correspond to winning.Then the probability of winning is m/n.
