    Correct option: C: 17/36

    Step-by-step explanation:

    To solve this problem, first we need to find the pairs of numbers, from one to six, that the product will be a number greater than 10:

    (2,6), (3,4), (3,5), (3,6), (4,3), (4,4), (4,5), (4,6), (5,3), (5,4), (5,5), (5,6), (6,2), (6,3), (6,4), (6,5), (6,6).

    We have 17 pairs of numbers.

    The total number of pairs than we can have rolling two number cubes, as each one has 6 numbers, is 6*6 = 36

    So the probability we want is the number of pairs with product greater than 10 (17 pairs) over the total number of pairs (36):

    P = 17/36

    Correct option: C
