Nonsmokers You are planning to open a new “Peking Duck” specialty restaurant in Beijing, and need to plan the seating arrangement. Unlike in Canada, you’ll need to plan for smokers as well as nonsmokers. While some nonsmokers do not mind being seated in the smoking section of a restaurant, you estimate that about 60% of the customers will demand a smoke-free area. Your restaurant will have 120 seats. How many seats should be in the nonsmoking area to be very sure of having enough seating there? Comment on the assumptions and conditions that support your model, and explain what “very sure” means to you.
