Question

While some nonsmokers do not mind being seated in a smoking section of a restaurant, about 60% of the customers demand a smoke-free area. A new restaurant with 120 seats is being planned.

How many seats should be in the nonsmoking area in order 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.

Answer 1

Answer: There are 72 seats in order to be very sure of having enough seating.

Explanation:

Since we have given that

Total number of seats is being planned = 120

Percentage of customers demand a smoke free area = 60%

So, Number of seats that should be in the non smoking area in order to be very of having enough seating would be

`(60)/(100)* 120\\\\=0.6* 120\\\\=72`

Hence, there are 72 seats in order to be very sure of having enough seating.
