Calculate the conditional probability
WebAug 24, 2024 · The conditional probability that event A occurs, given that event B has occurred, is calculated as follows: P (A B) = P (A∩B) / P (B) where: P (A∩B) = the probability that event A and event B both occur. P (B) = the probability that event B occurs. The following examples show how to use this formula to calculate conditional … WebJan 23, 2024 · A dot like n ⋅ j k relates to marginal sum. Then the probabilities could be estimated by ratios of those counts. P ( X = i Y = j, Z = k) = n i j k n ⋅ j k.
