58% of all americans are home owners. if 37 americans are randomly selected, find the probability that A. Exactly 20 of them are are how owners. B. At most 23 are are home owners. C. At least 22 of them are home owners.
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.

Let use denote X=the number of homeowners
n=sample size=37
p=probability of success= 58%=0.58
X follows a binomial distribution with n=37 and p=0.58
