दो घटनाएं A और B इस प्रकार है की `P(A)=1/4, P(A//B) = 1/2` तथा `P(B//A) = 2/3`, तो P(B) का मान है-

If P(A + B) = 2/3 and P(A - B) = 1/3, then P(B) = ?

It is given that the events A and B are such that P(A) = 1/4, P (A//B) = 1/2 and P(B//A) = 2/3 . Then P(B) is

If P(A) = 3/4 , P(B) = 2/5 , P(Ann B) = 1/4 then P(A uu B) =

It is given that events A and B are such that : P(A) = 1/4 ,P (A//B) =1/2 and P (B//A) =2/3 . Then P(B) is :

If A and B are two events such that P(A) = 1/4 , P(A/B) = 1/2 and P(B//A)= 2/3 then P(B) is equal to
