An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 140 lb and 191 lb. The new population of pilots has normally distributed weights with a mean of 150 lb and a standard deviation of 28.1 lb. a. If a pilot is randomly​ selected, find the probability that his weight is between 140 lb and 191 lb. The probability is approximately nothing. ​(Round to four decimal places as​ needed.)
