George grooms border collies. It is a challenging task and involves 5 steps. He has worked hard to balance the line; however, there is a lot of variability. Each stage in the process now handles between 20 and 24 border collies per hour depending on how complex the intake is. (Assume that each stage is independent and that it is equally likely that 20, 21, 22, 23, or 24 border collies get processed each hour at each stage.)

(Round your answer to 1 decimal place.)

If there is some inventory available for every position (do not worry about the start-up), what is the expected output per hour? Expected output = ______ border collies per hour
