Essay

The owner of a small convenience store is trying to decide whether to discontinue selling magazines.

Before making a final decision he decides that for one day he'll keep track of the number of customers and whether or not they buy a magazine.
-Assuming the owner is correct in thinking that 5% of the customers purchase magazines, how many customers should he expect before someone buys a magazine?
