Suppose the chance of getting flu is independent of each other. Suppose 20% of graduate school students nationwide develop influenza. Further, suppose we have a class of size 15. Let X be the number of students who get flu, calculate the following probabilities: Exactly 4 get influenza No more than 4 get influenza Less than 4 get influenza How many students should the teacher expect to be sick with influenza that year?
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.
