If P (A∩B) = 1/3, P(A∪B) = 5/6 and P(A) = 1/2, then which of the following is correct?
A and B are independent events
A and B are mutually exclusive events
P(A) = P(B)
P(A) < P(B)
If P(A) = P(B) = x and P(A∩B) = P(A'∩B') = 1/3, then x is equal to
1/2
1/4
1/3
1/6
If A and B are mutually exclusive events with P(A) = 1/2 x P(B) and AυB = S, then P(A) is equal to
2/3
3/4
