True statement A and true statement B are two independent events of an experiment.Let P(A)=0.3 , P(A∨B)=0.8 then P(A→B) is (where P(X) denotes probability that statement X is true statement)
Two aeroplanes I and II bomb a target in succession. The probabilities of l and II scoring a hit correctlyare 0.3 and 0.2, respectively. The second plane will bomb only if the first misses the target. The probability that the target is hit by the second plane is
A and B are events such that P(A)=0.42, P(B)=0.48 and P(A and B)=0.16. Determine P( not A).
If P(B)=34, P(A∩B∩ˉC)=13 and P(ˉA∩B∩ˉC)=13, then P(B∩C) is
