Five mice in a stable population of 500 are intentionally infected at r= 0 with a contagious disease to test a theory of epidemic spread that postulates that the rate of change in the infected population is proportional to the product of the number of mic who have the disease and the number of mice who do not have the disease.

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.
