WebBayes' theorem (or Bayes' Law and sometimes Bayes' Rule) is a direct application of conditional probabilities. The probability P (A B) of "A assuming B" is given by the formula. P (A∩B) = P (A B)·P (B). The left hand side P (A∩B) depends on A and B in a symmetric manner and would be the same if we started with P (B A) instead: WebBayes' theorem is a formula that describes how to update the probabilities of hypotheses when given evidence. It follows simply from the axioms of conditional probability, but can …
