    The probability that a person will hit a target in shooting practice is 0.3. If he shoots 10 times, then the probability of his shooting the target is

    A)  1                                            

    B)         \[1-{{(0.7)}^{10}}\]                             

    C)         \[{{(0.7)}^{10}}\]                 

    D)         \[{{(0.3)}^{10}}\]

    Correct Answer: B

    Solution :

    \[\because \]The probability that the person does not hit the target \[=1-0.3=0.7\] \[\therefore \] Probability of not shooting the target \[={{(0.7)}^{10}}\] \[\therefore \] Probability of shooting the target\[=1-{{(0.7)}^{10}}\]
