Suppose there is a 21.9% probability that a randomly selected person aged 25 years or older is a smoker. In addition, there is a 26.9% probability that a randomly selected person aged 25 years or older is male, given that he or she smokes. What is the probability that a randomly selected person aged 25 years or older is male and smokes? Would it be unusual to randomly select a person aged 25 years or older who is male and smokes
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.
