WebP(A/B) Formula is given as, P(A/B) = P(A∩B) / P(B), here ∩ symbol represents the intersection of event 'A' and event 'B'. P(A) is probability of event A happening, P(B) is the probability of event B happening … WebIf A and B are two events in a sample space S, then the conditional probability of A given B is defined as P ( A B) = P ( A ∩ B) P ( B), when P ( B) &gt; 0. Here is the intuition behind the formula. When we know that B has occurred, every outcome that is outside B should be discarded. Thus, our sample space is reduced to the set B , Figure 1.21.

WebP (A and B)/P (A) = P (B) is obtained from P (A and B)/P (B) = P (A) by multiplying both sides by the well-defined, nonzero quantity P (B)/P (A). So, assuming that P (A) and P (B) are nonzero, it's enough to test just one of P (A B) = P (A), P (B A) = P (B) to determine if A and B are independent.
