A group of seniors 65 and older, contain 1000 men and 900 women. It is known that 220 men and 252 women were regularly taking five or more drugs for chronic health problems. Suppose a person in this group is randomly selected. What is the probability that the person selected is a woman and takes five or more drugs per day? Suppose the person selected is a man. What is the probability that he takes five or more drugs per day? Suppose the person selected takes five or more drugs per day. What is the probability that the person is a woman?
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.
