A commuter airline receives an average of 10.9 complaints per day from its passengers. Using the Poisson formula, find the probability that on a certain day this airline will receive exactly 8 complaints. Round your answer to four decimal places. P(exactly 8)
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.
