Question

a. The events A and B are mutually exclusive. Suppose P(A) = .37 and P(B) = .38. What is the probability of either A or B occuring? (Round your answer to 2 decimal places.) Probability of either A or B b. What is the probability that neither A nor B will happen? (Round your answer to 2 decimal places.) Probability of neither A nor B

Answer 1

Answer)

Mutually exclusive means, P(A or B) = P(A) + P(B)

Given,

P(A) = 0.37

P(B) = 0.38

A)

P(A or B) = 0.37+0.38 = 0.75

B)

P(neither A nor B) = 1 - 0.75 = 0.25
