Find the probability that the firm receives 5 or more complaints in a day. Probability = B. Find the probability that the firm receives 20 or more complaints in a 4-day period. Probability =
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.
