Q. Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet. a. If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 220 feet? (Express the answer in four decimal points)  b. If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled greater than 290 feet? (Express the answer in four decimal points)   c. If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled between 200 feet and 300 feet? (Express the answer in four decimal points)
