In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Brianna 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. 341 visitors purchased no costume. 117 visitors purchased exactly one costume. 8 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase more than one costume as a percent to the nearest whole number.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
