The average number of miles driven on a full tank of gas in a certain model car before its low-fuel light comes on is 300. Assume this mileage follows the normal distribution with a standard deviation of 32 miles. Complete parts a through d below. a. What is the probability that, before the low-fuel light comes on, the car will travel less than 317 miles on the next tank of gas? (Round to four decimal places as needed.) b. What is the probability that, before the low-fuel light comes on, the car will travel more than 268 miles on the next tank of gas? (Round to four decimal places as needed.) c. What is the probability that, before the low-fuel light comes on, the car will travel between 266 and 286 miles on the next tank of gas? (Round to four decimal places as needed.) d. What is the probability that, before the low-fuel light comes on, the car will travel exactly 316 miles on the next tank of gas? (Round to four decimal places as needed.)
