B)the sum is less than 4.
C)the sum is 7.
D)the sum is 2.

  • Probability -

    Simply make a list of possibilities for each of your outcomes
    I will do C)
    To get a sum of 7 we could have:
    16 25 34 43 52 or 61 for a totol of 6 cases
    so prob(sum of 7) = 6/36 = 1/6

    do the others the same way.
