Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 240 feet and a standard deviation of 40 feet. Let X = distance in feet for a fly ball.

a.) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 212 feet? (Round your answer to four decimal places.)

b.) Find the 80th percentile of the distribution of fly balls. (Round your answer to one decimal place.)
