We want to find the number of ways in which 3r balls can be selected from 2r red balls and 2r blue balls. Find the generating function corresponding to the above problem in closed form.
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.
We want to find the number of ways in which 3r balls can be selected from 2r red balls
and 2r blue balls. Find the generating function corresponding to the above problem in closed form.
