Assume your dry cleaning business is a service that you’ve found the average person will use once a month in your area. You also discovered that customers want to drive less than 3 miles for dry cleaning. Get a map of your city and select a street corner at random. (We’ll assume that you will be able to build your dry cleaners there.) Use the census Website to estimate the population in your 3-mile radius. Consult the phone book to find other dry cleaners within that radius. Assuming you will evenly split the customers, what would be your share?
