Question

Your team examines the age of customers because they want to target the 32 and under demographic. What is the probability that a single randomly selected online transaction from the current week is from a customer that is less than 32 years old? Enter the probability below IF it can be computed with the given information/data. Enter "DNE" if the question cannot be answered with the given information/data.
