In a science class of 35 students, 15 are boys and 20 are girls. On a unit test, 5 boys and 8 girls made a B grade. If a student is chosen at random from the class, what is the probability of choosing a boy or a B student?
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.
