1(a) Define the independence of two events A' and B. Given that A and B are independent events in a sample space, such that P(A) is 2/5 and P(AUB) = 0.8,
find;
(i) P(B)
(ii) P(A'UB')
(b) In a certain town the probability that a person who owns a car is 0.25.
Given that the probability that a person who owns a car is a university
graduate is 0.2. Find the probability that a person selected at random
