Assume that 12 people, including the husband and wife pair, apply for 4 sales positions. People are hired at random. (1) What is the probability that both the husband and wife are hired? (2) What is the probability that one is hired and one is not?
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.
