Cоnsider the experiment оf tаking this exаm. Suppоse we model your score for this exаm as Y=5X, where X is a sum of N iid Bernoulli random variables each with parameter p=[p], 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. Find the variance of Y.
