If A and B are events such that P(A)=0.4, P(B)=0.5 and P(B/A)=0.6 , then P(bar(AnnB)) is :

Choose the correct answer : If P(A) = 0.8, P(B) = 0.5 P(B/A) = 0.4, find P(A nn B)

If P(A) = 0.8, P(B) = 0.5 and P (B|A) = 0.4 find: P(A|B)

If P(A) = 0.8, P(B) = 0.5 and P (B|A) = 0.4 find: P(AcapB)

If P(A) = 0.8, P(B) = 0.5 and P (B|A) = 0.4 find: P(AcupB)
