Let's say you are a cashier at Wal-Mart. It is 4:30pm and your shift ends at 5:00pm. The store policy is to close your checkout line 15 minutes before your shift ends (in this case 4:45) so that you can finish checking-out the customers already in your line and leave on-time. By examining overhead cameras, store data indicates that between 4:30pm and 4:45pm each weekday, an average of 10 customers enter any given checkout line. a. What is the probability that exactly 7 customers enter your line between 4:30 and 4:45? b. What is the probability that more than 10 people arrive? (Which means you will probably be on shift later than 5:00pm)
