A bakery is considering hiring another clerk to better serve

A bakery is considering hiring another clerk to better serve customers. To help with this decision, records were kept to determine how many customers arrived in 10-minute intervals. Based on 100 ten-minute intervals, the following probability distribution and random number assignments developed. Suppose the next three random numbers were .18, .89 and .67. How many customers would have arrived during this 30-minute period?

Solution

Since the next three arrivals are 0.18, 0.89, 0.67 the number of customers would have arrived is

7+8+9=24
