WebFeb 22, 2016 · In words, Bayes’ theorem asserts that:. The posterior probability of Event-1, given Event-2, is the product of the likelihood and the prior probability terms, divided by the evidence term.; In other words, you can use the corresponding values of the three terms on the right-hand side to get the posterior probability of an event, given another event.
