Suppose that the number of customers visiting a fast food restaurant in a given day is N~ - Poisson(1). Assume that each customer purchases a drink with probability p, independently from other customers, and independently from the value of N. Let X be the number of customers who purchase drinks. Let Y be the number of customers that do not purchase drinks; so X+Y = N. Are X and Y independent? O can't be determined O works on both cases o They are not independent O They are independent
