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. You may round your answer to two decimal places. P(T < 685)≈
