(8) The litter size of the Montreal common grey squirrel is a random variable X with probability function given by X 1 2 3 4 P(X =x} 1/8 3/8 3/8 1/8 Suppose there are 25 pregnant squirrels this spring in Dominion square, each of whose litter size has the probability function given above. Let Y be the total number of offspring of these 25 squirrels. Using the Central Limit Theorem, find (approximately) P{Y 2 68}
