A gasoline tank for a certain car is designed to hold17.0gal of gas. Suppose that the variablex= actual capacity of a randomly selected tank has a distribution that is well approximated by a normal curve with mean17gal and standard deviation0.1gal. (Round all answers to four decimal places.)(a) What is the probability that a randomly selected tank will hold at most16.8gal? P(x≤16.8) = (b) What is the probability that a randomly selected tank will hold between16.7and17.2gal? P(16.7≤x≤17.2) = (c) If two such tanks are independently selected, what is the probability that both hold at most17gal? P(x≤17) =
