Naive Bayes The joint probability P(A,B) = P(B|A)*P(A) = P(A|B)*P(B) combines the two equations on the right to get the following formula: P (a| b) indicates the probability of a in the case of B. P(A|B) = [P(B|A)*P(A)] / P(B) Let's have A visual understanding of this formula. As shown in the figure ...
