Cоnsider the experiment оf tаking this exаm. Suppоse we model your score for this exаm as Y=5X, where X is a discrete uniform random variable over {0,1,...,N}, and N is the total number of questions. Note that X represents a random variable which is the total number of questions you get right. Consider another person taking this exam, and their exam score W has exactly the same distribution as yours, but W is independent of your score Y. Find the probability that X=W.
