    Question

    If two dice are rolled simultaneously, what is the

    probability that the sum of the numbers on the two dice is greater than or equal to 10?
    A 1/8 Correct Answer Incorrect Answer
    B 1/6 Correct Answer Incorrect Answer
    C 1/5 Correct Answer Incorrect Answer
    D 5/12 Correct Answer Incorrect Answer

    Solution

    When two dice are rolled together at once, total number of possible events = 62 = 36 Favourable events = {(4,6), (5, 5) (5, 6), (6, 4), (6, 5), (6, 6)} So, number of favourable events = 6 Therefore, required probability = (6/36) = (1/6)
