    In a cricket match, a batswoman hits a boundary 6 times out of 30 balls she plays. Find the probability that she did not hit a boundary.

    A)  \[\frac{1}{5}\]                                  

    B)         \[\frac{4}{5}\]                  

    C)         \[\frac{2}{5}\]                                  

    D)         \[\frac{3}{5}\]

    Correct Answer: B

    Solution :

    Total number of balls = 30 Number of times the boundary is not hit \[30-6=24\] \[\therefore \]P (boundary is not hot) \[=\frac{24}{30}=\frac{4}{5}\]
