Two aeroplanes bomb a target; P(I hits)=0.3, P(II hits)=0.2; II bombs only if I misses.

Question

Two aeroplanes bomb a target; P(I hits)=0.3, P(II hits)=0.2; II bombs only if I misses. Find the probability the target is hit by the second plane.

Accepted Answer

$$P = P(\overline I)\times P(II) = 0.7\times0.2=0.14$$
