  • question_answer The probability of getting the sum more than\[7\] when a pair of dice is tossed is

    A) \[\frac{1}{9}\]                                   

    B) \[\frac{1}{4}\]

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

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

    Correct Answer: D

    Solution :

     Sum of \[7\] can be obtained when\[(2,\,\,6),\,\,(3,\,\,5)(3,\,\,6),\,\,(4,\,\,4),\]\[(4,\,\,5),\,\,(4,\,\,6)(5,\,\,3)\]\[(5,\,\,4)(5,\,\,5)(5,\,\,6)(6,\,\,2)(6,\,\,3)\]\[(6,\,\,4)(6,\,\,5)(6,\,\,6)\] \[\therefore \]Probability of sum\[>7=\frac{15}{36}=\frac{5}{12}\]
