Webb12 aug. 2024 · Anne Marie Helmenstine, Ph.D. Updated on August 12, 2024. Bayes' theorem is a mathematical equation used in probability and statistics to calculate conditional probability. In other words, it is used to calculate the probability of an event based on its association with another event. The theorem is also known as Bayes' law or Bayes' rule. WebbP (A and B) = P (A)P (B). Without the assumption of independence, we have to modify this rule by replacing one of the individual probabilities by a conditional probability: P (A and …
