Larry Ellison starts a company that manufacturers high-end custom leather bags. He hires 2 employees. Each employee only begins working on a bag when a customer order has been received and then she makes the bag from beginning to end. The average production time of a bag is 1.8 days with a standard deviation of 2.1 days. Larry expects to receive one customer order per day on average. The interarrival times of orders have a coefficient of variation of 1.

What is the expected duration, in days, between when an order is received and when production begins on the bag? Round to nearest integer.
