Hello,
I am referring to question #14 on page 298 of The Official Guide Book. The question asks "Let A, B, C and D be events for which P(A or B) = 0.6, P(A) = 0.2, P (C or D) = 0.6, and P© = 0.5. The events A and B are mutually exclusive, and the events C and D are independent. a) Find P(B) which I believe is 0.4, but how do you get P(D) = 0.2?
Thanks.
