WebbThe probability of A or B, occurs, but not both. Let A and B be two events. Suppose that P (A) = 0.4, P (B) = 0.5 and P (A intersect B) = 0.1.Find the probability that A or B occurs, but not both. I have been working on this one exercise for a while now and cant really get any further. This is what I have now; WebbA and B are independent but not equally likely. Example 4: The probability that at least one of the events A and B occurs is 0.6. If A and B occur simultaneously with probability 0.2. Then what is P ( A ―) + P ( B ―)? Solution: Given : P (A ∪ B) = 0.6, P (A ∩ B) = 0.2 ∴ P (A ∪ B) = P (A) + P (B) − P (A ∩ B) 0.6 = P (A) + P (B) − 0.2
