If `P(A)=2/5, P(A nn B)=3/10` then `P(B|A)`

A and B are events such that P(A)=0.3, P(B)=0.25, P(A nn B)=0.2 then P(bar(A)/bar(B))=

If P(A uu B)=0.8,P(A nn B)=0.3 then P(bar(A))+P(bar(B))=

If P(A) = (4)/(5), P(B) = (2)/(5), P(A nn B) = (1)/(2) then P(A uu B) is equal to .

If 4 P(A) = 6 P(B) = 10 P(A nn B) = 1 then P((B)/(A))=

If P(A) = 0.7, P(B) = 0.4, P(A nn B) = 0.3, then P(A nn B') =

If A, B are two equiprobable events such that P(A nn B)=1/4 and P(A' nn B')=1/5 then P(A) = ____________.

If two events A and B are such that P(A')=0.3, P(B)=0.4 and P(A nn B')=0.5 , then P((B)/(A uu B')) equals

If (A)=3/10,P(B)=2/5 and P(AcupB)=3/5 then P(B/A)+P(A/B) equals to

If A and B are two events such that P(A)=1/4, P(B)=1/2, P(A uu B)=5/8 then P(A nn B)=
