WebBayes’ theorem converts the results from your test into the real probability of the event. For example, you can: Correct for measurement errors. If you know the real probabilities and … WebAnd it calculates that probability using Bayes' Theorem. Bayes' Theorem is a way of finding a probability when we know certain other probabilities. The formula is: P (A B) = P (A) P (B A) P (B) Which tells us: how often A happens given that B happens, written P (A B), When we know: how often B happens given that A happens, written P (B A)
