WebMar 12, 2024 · Conditional probability is used to find out the probability of some event happening given that some other event has happened. Easy right? Therefore, conditional probability find that Y = y if X = x. Formula: P (Y = y X = x) or. P (Y = y X = x) = P (Y = y, X = x)/P (X = x) Finally, a conditional probability is only defined when P (X = x) > 0.
