    They had 54 twos and 62 threes.

    54 + 62 = 116 outcomes of either 2 or 3

    The probability is the number of outcomes divided by the total number of rolls.

    116 / 360 = 0.32

    The answer is A.

    0.32.

    Step-by-step explanation:

    Prob (Rolling a 2) = number of 2's rolled / total number of rolls

    = 54/360 = 0.15

    Similarly Prob (rolling a 3) = 62/360 = 0.17.

    So the probability of a 2 or a 3 = 0.15 + 0.17 = 0.32.
