Four actions are to be performed in a definite order. There are five possibilities for the first action; corresponding to each of these possibilities are two possibilities for the second action; corresponding to each of these possibilities are two possibilities for the third action; and corresponding to each of these possibilities are four possibilities for the fourth action. How many possibilities are there altogether for the four actions?
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.
