The random variable X represents the number of cherries in a cherry puff, and has the probability distribution ƒ(4) = 0.2, ƒ(5) = 0.4, ƒ(6) = 0.3, ƒ(7) = 0.1, where f(x) is the probability that there are à cherries in the cherry puff. Find the probability that the average number of cherries in 36 cherry puffs is less than 5.5.
