Question: Camille owns Crunch Code, a company that provides quick programming solutions. Clients send projects to Crunch via their web page and a programmer develops the needed code as quickly as possible. Camille has five programmers, who do all of the coding. On average, a project arrives once every 4.8 hours, with a standard deviation of 6.00 hours. Each project is assigned to one programmer and that programmer takes on average 19.2 hours to complete each project with a standard deviation of 19.2 hours.
How many uncompleted projects does Crunch Code have in the system on average at any given time? (Include projects waiting for a programmer as well as those being programmed.)
