Events A and B are such that P(A)=1/2, P(B)=7/12 and P(not A or not B) =1/4 . State whether A and B are independent.

If P(A) = 1/2 , P(B) = 7/12 and P(not A or not B) = 1/4 , then A and B are independent events.

If P(A)=(1)/(4), P(B)=(1)/(13) and P(AcapB)=(1)/(52) , then the value of P(overline(A)capoverline(B)) , is A. (3)/(13) B. (5)/(13) C. (7)/(13) D. (9)/(13)

If P(A) = 7/13, P(B) = 9/13 and P(A cup B) = 12/13 where A and B are independent events then find P(A/B) .

If P(A)=3/4 and P(B)=1/4 , find P(AcapB) if A and B are independent events.
