A car dealer is trying to sell five used cars. She attempts to sell a car to each customer that walks in. Suppose that only 7% of all the potential customers are willing and able to purchase a car, and assume that each customer acts independently of one another. Let X denote the number of customers that walk in before all five cars are sold. What is the distribution of X? What is the probability that the last car is sold to the 100th customer?

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.
