In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Luke sets up a website where players can buy
and sell these costumes online. Information about the number of people who visited
the website and the number of costumes purchased in a single day is listed below.

204 visitors purchased no costume.
209 visitors purchased exactly one costume.
27 visitors purchased more than one costume.

Based on these results, express the probability that the next person will purchase one
or more costumes as a fraction in simplest form.
