A doctor wants to know the probability that an infection will occur after performing a particular procedure. In order to calculate this probability he checks medical records and finds that a total of 3,500 of these procedures were conducted in the past year and there were infections following 8 of these procedures.

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.
