A engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 120 lb and 161 lb. The new population of pilots has normally distributed weights with a mean of 126 lb and a standard deviation of 29.5 lb. A. If a pilot is randomly selected, find the probability that his weight is between 120lb and 161lb B. If 33 different pilots are randomly selected, find the probability that their mean weight is between 120lb and 161 lb

Please show work so I can try to figure it out in the future
