Solution

The correct option is A independent
P(A+B) = P(A) + P(B) - P(AB)
5/6 = 1/2 + P(A) -1/3
P(A) = 2/3
Therefore P(A)*P(B) = P(AB)
Hence A and B are independent

The correct option is A independent
P(A+B) = P(A) + P(B) - P(AB)
5/6 = 1/2 + P(A) -1/3
P(A) = 2/3
Therefore P(A)*P(B) = P(AB)
Hence A and B are independent
