Bayes' Theorem

A technique for estimating the conditional probability of a cause given that a particular event has occurred. The theorem states that the probability of cause Bj given the observation of event A is equal to the joint probability of A and Bj divided by the sum of the joint probabilities of A with B1 through Bn. The theorem is named after Thomas Bayes, an 18th century English clergyman who was interested in mathematics.
