Two aeroplanes I and II bomb a target in succession. The probability of I and II scoring a hit correctly are 0.3 and 0.2, respectively. The second plane will bomb only if the first misses the target. Find the probability that the target is hit by the second plane, is
(a) 0.06
(b) 0.14

Please answer the below question
Assertion : An observer is moving due east and wind appears him to blow from north. Then the actual direction of air blow is towards south-east.
Reason : Because \(\vec V_R = \vec V_A - \vec V_M \) where \(\vec V_R\) is the relative velocity of wind with respect to man, \(\vec V_A =\) actual velocity of wind (w.r.t. ground) and \(\vec V_M =\) velocity of man w.r.t. ground.
(a) A
(b) B
(c) C
(d) D
