Probability of a Small Straight = Total Combos of 1-2-3-4, 2-3-4-5, 3-4-5-6/All Possible Rolls

Total Combos of 1-2-3-4, 2-3-4-5, 3-4-5-6 = Total Combos of 1-2-3-4 * 3

Total Combos of 1-2-3-4 = 4 (1-4) * 4 (1-4) * 4 (1-4) * 1 choice left * (6 - 1 not Lg St)

Total Combos of 1-2-3-4 = 4 * 4 * 4 * 1 * 5

Total Combos of 1-2-3-4 = 320

Total Combos of 1-2-3-4 * 3 = 320 * 3

Total Combos of 1-2-3-4, 2-3-4-5, 3-4-5-6 = 960

Total Possible Die Roll Combos = 6 * 6 * 6 * 6 * 6

Total Possible Die Roll Combos = 7,776
