The Denver Post reported that, on average, a large shopping center had an incident of shoplifting caught by security 2.3 times every four hours. The shopping center is open from 10 A.M. to 9 P.M. (11 hours). Let r be the number of shoplifting incidents caught by security in an 11-hour period during which the center is open. (a) Explain why the Poisson probability distribution would be a good choice for the random variable r. Frequency of shoplifting is a rare occurrence. It is reasonable to assume the events are independent.Frequency of shoplifting is a common occurrence. It is reasonable to assume the events are independent.    Frequency of shoplifting is a common occurrence. It is reasonable to assume the events are dependent.Frequency of shoplifting is a rare occurrence. It is reasonable to assume the events are dependent.

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.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
