The remaining slice is gold and awards a 100% discount! What is the probability that a customer gets at least a 40% discount? Solution If all the slices are of equal size, the probability of landing in any one of them is the same,i.e., 1/12 since there are 12 slices. At least 40% discount means 40 or 100. There are 3 such slices. So the required probability is 3/12 (option B).
