         If two dice are thrown once, then the probability of getting a total of 10 is:

    A) \[\frac{5}{12}\]

    B) \[\frac{7}{12}\]

    C) \[\frac{1}{12}\]

    D) None of these

    Correct Answer: C

    Solution :

    [c] Total no. of sample outcomes \[=6\times 6=36\]
    Favourable outcomes
    \[\{(4,6),(5,5),(6,4)\}\]
    \[\therefore \] Total no. of favourable outcomes =3
    So. required probability \[=\frac{3}{36}=\frac{1}{12}.\]
