In this exercise, the random variable n represents the number of units of a product sold per day in a store. The probability distribution of n is given by P(n). Find the probability that two units are sold in a given day [P(2)] and find P(0) + P(1) + P(2) + P(3) + . . . . P(n) = 1 6 5 6 n P(2) = [infinity] P(n) n = 0 =
