A company sells apples in packages of 4. The masses of the individual apples are normally distributed with a mean of 175 g and a standard deviation of 15 g. Assume that the weights of apples are independent from
each other.
Let T = the total weight of 4 randomly selected apples.
Find the probability that the total mass is less than 685 g

Restrictions on f(x) = 1/x+5 and g(x) = x-2
