Webb‌The conditional probability of an eventBis the probability that the event will occur given the knowledge that an eventAhas already occurred. It is denoted by P(B A). So now, The joint probability of two dependent events becomes ‌P(A ∩B) = P(A)P(B A) 6.Bayes Theorem We know that, P(A ∩B) = P(A)P(B A)and P(B ∩A) = P(B)P(A B) WebbLuckily, the mathematical theory of probability gives us the precise and rigorous tools necessary to reason about such problems with relative elegance. The conditional probability means "what is the probability of event A given that we know event B occurred". Its mathematical definition is: Notes: Obviously, this is only defined when . brighton armory
