    If a dice is thrown 5 times, then the probability of getting 6 exact three times, is

    A)                 \[\frac{125}{388}\]             

    B)                 \[\frac{125}{3888}\]

    C)                 \[\frac{625}{23328}\]         

    D)                 \[\frac{250}{2332}\]

    Correct Answer: B

    Solution :

                    Required probability \[={}^{5}{{C}_{3}}{{\left( \frac{1}{6} \right)}^{3}}{{\left( \frac{5}{6} \right)}^{2}}=\frac{125}{3888}.\]
