A gasoline tank for a certain car is designed to hold 15.0 gal of gas. Suppose that the variable x = actual capacity of a randomly selected tank has a distribution that is well approximated by a normal curve with mean 15 gal and standard deviation 0.1 gal. (Round all answers to four decimal places.) (a) What is the probability that a randomly selected tank will hold at most 14.8 gal? P(x ≤ 14.8) = (b) What is the probability that a randomly selected tank will hold between 14.7 and 15.1 gal? P(14.7 ≤ x ≤ 15.1) = (c) If two such tanks are independently selected, what is the probability that both hold at most 15 gal?
