You are given the information that P(A) = 0.30 and P(B) = 0.40.
(1) Do you have enough information to compute P(A or B)? Explain.
(A) Yes. This probability is equal to 0.70.
(B) No. You need to know the value of P(A and B).
(C) No. You need to know the value of P(A) + P(B).
(D) No. You need to know the value of P(A) - P(B).
(2) If you know that events A and B are mutually exclusive, do you have enough information to compute P(A or B)? Explain.
(A) No. Knowing the events are mutually exclusive does not provide any extra information.
(B) Yes. P(A and B) = 0, so P(A or B) = P(B) - P(A).
(C) Yes. P(A and B) = 0, so P(A or B) = P(A) + P(B).
(D) Yes. P(A and B) = 0.12, so P(A or B) = P(A) + P(B) - 0.12.
