The university police department must write, on average, five tickets per day to keep department revenues at budget levels. Suppose the number of tickets written per day follows a Poisson distribution with a mean of 9.3 tickets per da the probability that exactly four tickets are written on a randomly selected day from this distribution.

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.
Binomial Distribution
