Two independent events A and B have probabilities 0.4 and 0.5. The probability that exactly one of them occurs is:
Correct Answer: Option C
Explanation:
P(Exactly one) = P(A) + P(B) - 2*P(A ∩ B) = 0.4 + 0.5 - 2*(0.4*0.5) = 0.9 - 0.4 = 0.5.
P(Exactly one) = P(A) + P(B) - 2*P(A ∩ B) = 0.4 + 0.5 - 2*(0.4*0.5) = 0.9 - 0.4 = 0.5.
