Suppose that A and B are independent events such that P(A) = 0.20 and P(B complement) = 0.70.
Find the probability of the intersection of A and B
Find the probability of the union of A and B
This solution shows how to calculate the probabilities of the union and intersection of independent events. Two events are considered. The problem gives the probability of A and the probability of the complement of B. From this information plus the knowledge that the events are independent, we can find the probabilities of both the union and intersection of A and B.
