For the lucky draw, the prize committee of a school has decided to randomly purchase 3 cell phones of a certain brand from the 6 sets available at the shop. Unknowing to the committee, 2 of the sets are of imitation brand. Defining X as the number of genuine sets purchased, determine a) the probability distribution of X. b) the cumulative distribution of X. c) the mean and variance of X.

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.
