    Three identical dice are rolled. The probability that same number will appear on each of them will be:

    A)  \[\frac{1}{6}\]                  

    B)         \[\frac{1}{36}\]               

    C)         \[\frac{1}{18}\]               

    D)         \[\frac{3}{28}\]

    Correct Answer: B

    Solution :

    Total number of cases, \[n(S)={{6}^{3}}\] Total number of favourable cases, in which all three dice have Same number, \[n(F)=6\] \[\therefore \]Required probability \[=\frac{6}{{{6}^{3}}}\]                                                 \[=\frac{1}{36}\]
