Suppose that 60% of the people who own a GM car buy a GM car for their next vehicle. Also, suppose that 90% of the people who own non-GM cars by a non-GM car for their next vehicle. Let x and y denote the number of GM car owners and non-GM car owners respectively. If u and v denote the corresponding number of GM and non-GM car owners after buying their next car. (a) write a matrix equation relating to x,y, to u,v (b) of 100 people own a GM car and 200 people own a non-GM car, how many people will own each type of car after their next purchase?
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.
