(d) What is the probability there are 3 cars in the drive-thru? (e) What is the probability there are at least 5 cars in the drive-thru? (f) What is the probability there are less than 2 cars in the drive-thru? 4.
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.
