To find the probability that there will be at least three loaves left over, we need to add up the probabilities for X = 3, 4, 5, 6, 7, and 8. Adding these probabilities gives 0.10 + 0.15 + 0.20 + 0.15 + 0.10 + 0.05 = 0.75. Therefore, the probability that there will be at least three loaves left over is 0.75, which corresponds to answer choice D.
