Assume that the causes of a disease are 29% of the time associated with diet and 71% of the time associated with genetics, and that the causes of the disease are independent from each other. What is the expected number of cases of the disease due to genetics before the first case appears due to diet?
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.
