Answer: 0.0129
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Sample size : 
Let X be the random variable that represents the age of of the fleets.
Z-score : 
For x = 14

By using standard normal distribution table , the probability that the average age of these 40 airplanes is at least 14 years old will be

Hence, the the probability that the average age of these 40 airplanes is at least 14 years old =0.0129
