Answer:

DNE

Step-by-step explanation:

The information is not enough to find the required probability.

We need the mean age and standard deviation of customers.

Since to calculate the probability it would come being applying the formula of z:

z = x - m / sd

where m is the mean and sd is the standard deviation, then using the normal distribution table, we could calculate the probability for that z-score.
