    A)  \[\frac{1}{6}\]

    B)  \[\frac{3}{36}\]

    C)  \[\frac{1}{36}\]

    D)  \[\frac{2}{3}\]

    Correct Answer: C

    Solution :

     Number of ways of getting the same digit on all the three dice {(1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5) and (6, 6, 6)} Total number of ways \[={{6}^{3}}=216\] Thus, required probability \[=\frac{6}{216}=\frac{1}{36}\]
