Whenever we aim for a target ,there are two possible event to occur ,
either hitting the target which is denoted by
or missing the target which is denoted by
Here, the probability of hitting a target
and the probability of missing a target
Now ,we have
So,
Therefore,least number of shots required so that the probability of his hitting the target at least once is greater than is .
Hence option (B) is the correct option.
