5) If P(A) = 0.45, P(B) = 0.41, and P(A or B) = 0.86, are A and B mutually exclusive? A) Yes B) No 6) Let A and B be events with P(A) = 0.9, P(B) = 0.4, and P(A and B) = 0.36. Are A and B independent? A) No B) Yes

Step 1
In other words, P(A and B) = 0. However, we can calculate P(A and B) using the formula P(A or B) = P(A) + P(B) - P(A and B). Substituting the given values, we get 0.86 = 0.45 + 0.41 - P(A and B), which gives P(A and B) = 0. So, A and B are not mutually exclusive. Show more…

Let P(A) = 0.40, P(B) = 0.40, and P(A ∩ B) = 0.18. a. Are A and B independent events? 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. b. Are A and B mutually exclusive events? 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. What is the probability that neither A nor B takes place?
