Let P ( A ) = 0.39, P ( B ) = 0.34, and P ( A ? B ) = 0.04. a. Are A and B independent events? Yes b
Let P(A) = 0.39, P(B) = 0.34, and P(A ? B) = 0.04.
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? (Round your answer to 2 decimal places.)
Probability
Let P(A) = 0.39, P(B) = 0.34, and P(A ? B) = 0.04.
