A store has 12 cars for sale. 5 are new, 4 are accident cars and 3 are used but in good condition. If 3 cars are selected at random for shipping to a customer. Let X be the number of new cars in the shipment. If a customer wants one new car, one accident car and one used car. In how many ways can this selection be done? Find the probability function for 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.
