In statistics and probability theory, the Bayes’ theorem (also known as the Bayes’ rule) is a mathematical formula used to determine the conditional probability of events. Essentially, the Bayes’ theorem describes the probability of an event based on prior knowledge of the conditions that might be relevant to the event. WebJul 28, 2024 · Abstract. Bayes’ theorem (or Bayes’ rule) is frequently used as a means of estimating and updating probability given incomplete information. There are many forms this updating can take, and it has been applied to many problems in data science, engineering, astronomy, economics, biology, sociology, and many other disciplines. images of people of different cultures
