Applying properties of conditional probability[Hinglish]| Probability | Grade 12| Math| Khan Academy

From the creator

In this video, we apply the fundamental properties of conditional probability to solve various problems. We'll use the formula P(A|B) = P(A intersect B) / P(B) to calculate conditional probabilities when the probabilities of individual events and their intersection or union are known. We work through several examples demonstrating how to find P(E|F), P(F|E), P(A intersect B), P(A|B), and P(A U B) under different given conditions. Courses on Khan Academy are always 100% free.
