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.
There are two type of variables : Continuous variables and discrete variables.
Continuous variables can take any value within the range (no specified count) while discrete variables take a finite number of values. For example, number obtained on a die is discrete variable as it takes 1 , 2 ,3,4,5,6 values only while amount of claim can take any values with no specified number of count, so it is continuous random variable.
