Question 1 1 pts Apple Stores all over the world start to re-open with certain precautions against the COVID-19. Each customer has to be scanned for temperature before being admitted to the store. In addition, in order to prevent crowds within the store, the store manager allows only 5 customers at a time, as there are only 5 Apple geniuses to help the customers. As a result, queues are started to form in front of every store, even though a new iPhone/iPad has not been launched recently. Each customer on average spends 20 minutes in the store. If a new customer joins the queue every 5 minutes, what is the average number of people waiting in the queue at any given time? (Round your final answer to the nearest three decimal points, small errors will not be penalized. E.g. 1.233 and 1.234 are both correct)
