In an average year during 1995–1999, smoking caused 442,398 deaths in the United States. Of these deaths, cardiovascular disease accounted for 148,605, cancer for 155,761, and respiratory diseases such as emphysema for 98,007. (a) Find the probability that a smoking-related death was the result of either cardiovascular disease or cancer. (b) Determine the probability that a smoking-related death was not the result of respiratory diseases.
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.
