  • question_answer
    In a single throw of two dice, the probability of getting more than 7 is                                           [MP PET 1991]

    A)                 \[\frac{7}{36}\]    

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

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

    D)                 \[\frac{5}{36}\]

    Correct Answer: C

    Solution :

               Required probability is            \[P(\text{getting}\,8)+P(9)+P(10)+P(11)+P(12)\]                 \[=\frac{5}{36}+\frac{4}{36}+\frac{3}{36}+\frac{2}{36}+\frac{1}{36}=\frac{15}{36}=\frac{5}{12}\].
