(a) Do you have enough information to compute P(A or B)? Explain. O No. You need to know the value of P(A) - P(B). O No. You need to know the value of P(A) + P(B). O Yes. This probability is equal to 0.70. O No. You need to know the value of P(A and B). (b) If you know that events A and B are mutually exclusive, do you have enough information to compute P(A or B)? Explain. - O Yes. P(A and B) = 0, so P(A or B) = P(B) = P(A). O No. Knowing the events are mutually exclusive does not provide any extra information. O Yes. P(A and B) = 0, so P(A or B) = P(A) + P(B). O Yes. P(A and B) = 0.12, so P(A or B) = P(A) + P(B) -0.12. Need Help? Read It
