Suppose that 30 percent of an adult population have an infectious disease and 40 percent have a chronic disease. Assume that having an infectious disease is independent from having a chronic disease. For each of the questions below perform the calculation using appropriate statistical notation. a. What is the probability that a person selected at random will have both diseases? b. What is the probability of having the infectious disease for people with the chronic disease? c. What is the probability of having the infectious disease for people without the chronic disease? d. What is the probability of not having the infectious disease for people with the chronic disease?
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.
Suppose that 30 percent of an adult population have an infectious disease and 40 percent have a
chronic disease. Assume that having an infectious disease is independent from having a chronic
disease. For each of the questions below perform the calculation using appropriate statistical
notation.

b. What is the probability of having the infectious disease for people with the chronic disease?
c. What is the probability of having the infectious disease for people without the chronic disease?
d. What is the probability of not having the infectious disease for people with the chronic
disease?
