Bayes' theorem
noun Etymology: Thomas Bayes died 1761 English mathematician Date: 1865 a theorem about conditional probabilities: the probability that an event A occurs given that another event B has already occurred is equal to the probability that the event B occurs given that A has already occurred multiplied by the probability of occurrence of event A and divided by the probability of occurrence of event B
