Example 3 I’m not sure how to start it
If A and B are independent events, then the probability that both A and B occur is: separate probabilities of the individual events together. This works out only slightly conditional probability- The probability that an event, B, occurs given that an event, A, In general, to find the probability of more than one event occurring, we multiply the has occurred, is called the conditional probability of B given A and is written BIA. differently when the events are independent or dependent. If A and B are dependent events, then the probability that both A and B occur is: ore events, in which the occurrence of P(A and B) = P(A) u P(B) P(A and B) = P(A) u P(B|A) (a) P(blue, then red) (b) P(clear, then clear) Example 4: There are 15 marbles in a bag, 5 are blue, 3 are red, and 7 are clear. If a marble is pulled from the bag, and then a second marble is pulled out, find: (b) P(clear, then clear) (a) P(blue, then red)
