When the wheel is spun, a ball rolls along the outer edge of the wheel until it falls into one of the numbered slots. What is the probability that the ball lands on an even number or a black 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.
