A bingo machine has balls numbered from 1 to 75, and uses a physical process to randomly select 1 of those balls at a time. Each ball is equally likely to be selected. In this machine, for the first ball selected, what is P("number on the ball is below 20")? Please give your answer as a decimal, rounded to 2 places after the decimal point.
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.
