In your Easter Egg decorating stall, suppose that when your queuing area is filled, you assume customers walk past your stall. Assume, for simplicity, your 3 stations are considered to be one server. A preliminary study found that customers arrive at a Poisson rate of 3 per hour. The time required to serve the customer is exponentially distributed with a mean of 15 minutes per customer. You have decided to provide a waiting line of sufficient length such that less than 1% of arriving customers will leave. What is the minimum number of waiting spaces that will satisfy the objective?
