WebApr 8, 2012 · The Bayes rule is a way to relate these two probabilities. P (smoker evidence) = P (smoker)* p (evidence smoker)/P (evidence) Each evidence may increase or decrease this chance. For example, this fact that he is a man may increase the chance provided that this percentage (being a man) among non-smokers is lower.
