A: GivenP(A)=0.29P(B)=0.32A and B are mutually exclusive events

Question

The probabilities that stock A will rise in price is 0.40 and that stock B will rise in price is 0.60. Further, if stock B rises in price, the probability that stock A will also rise in price is 0.50.

a. What is the probability that at least one of the stocks will rise in price? (Round your answer to 2 decimal places.)

b. Are events A and B mutually exclusive?

multiple choice 1

Yes because P(A | B) = P(A).
Yes because P(A ∩ B) = 0.
No because P(A | B) ≠ P(A).
No because P(A ∩ B) ≠ 0.

c. Are events A and B independent?

multiple choice 2

Yes because P(A | B) = P(A).
Yes because P(A ∩ B) = 0.
No because P(A | B) ≠ P(A).
No because P(A ∩ B) ≠ 0.
