Let A and B be two events. If P (A) = 0.2, P (B) = 0.4, P (A∪B) = 0.

1.	Let A and B be two events. If P (A) = 0.2, P (B) = 0.4, P (A∪B) = 0.6, then P (A \| B) is equal to(A) 0.8(B) 0.5(C) 0.3(D) 0
Answer» The correct answer is (D). From the given data P (A) + P (B) = P (A∪B). This shows that P (A∩B) = 0. Thus P (A \| B) = P(A∩B)/P(B) = 0

Let A and B be two events. If P (A) = 0.2, P (B) = 0.4, P (A∪B) = 0.6, then P (A | B) is equal to(A) 0.8(B) 0.5(C) 0.3(D) 0

Answer»

The correct answer is (D). From the given data P (A) + P (B) = P (A∪B).

This shows that P (A∩B) = 0. Thus P (A | B) = P(A∩B)/P(B) = 0
