Probability of picking balls from bags [Hinglish] | Probability | Grade 12 | Math | Khan Academy

In this video, we solve several classic probability problems involving drawing balls from different bags, which are perfect applications of Bayes' theorem and the law of total probability. We'll tackle scenarios where a bag is chosen at random before a ball is drawn, and then use the outcome of the draw to determine the probability it came from a specific bag. We'll also look at a problem where the composition of the urn changes based on the first draw. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
