fred owns an oil change shop and is doing some research on car colors. saturdays are super busy, so currently there are 30 cars that are in line for an oil chang: 5-red, 7-black, 12-blue, and 6-white. Fred has 4 lanes to do oil changes so there are always 4 cars chosen at a time. (now remember that once the cars are picked for an oil change they do not return- aka without replacement) what is the probability that the all 4 cars getting an oil change are blue? what is the probability that there are 2 cars that are white and 2 cars that are not white?
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.
