The soda machine outside the lecture hall sees a steady stream of customers throughout the day. While the machine takes 4 seconds to deliver a can of carbonated sugar water once the button is pressed, the student customers introduce variation into the delivery process by pondering their selection for a while. Thus, we can safely say that the service time is governed by a negative exponential probability distribution that averages 10 seconds. Over the course of a twelve-hour lecture day, students arrive at the rate of 240 per hour, Poisson distributed of course.


On average, how many students are standing directly in front of the soda machine?

• 2

• 1.33

• 0.67

• 0.5
