There are 56 possible combinations when drawing two chips. Remember that you cannot draw two of the same chips from the bag, so 11, 22, 33, 44, 55, 66, 77, and 88 are not possible. Therefore, 20 of 56 combinations are divisible by 3, or approximately 36 percent. 12,13,14,15,16,17,18 21,23,24,25,26,27,28 31,32,34,35,36,37,38 41,42,43,45,46,47,48 51,52,53,54,56,57,58 61,62,63,64,65,67,68 71,72,73,74,75,76,78 81,82,83,84,85,86,87
