In the population of Dry Gulch, 75% of the population are rancher and 90% are beer drinkers. Only 5% of the population is not a rancher and does not drink beer. Suppose that R is the event " individual is a rancher" and B is the event "individual drinks beer". Answer the following questions. a) and individual that drinks beer and is not a rancher would be included in which event? b) the probability that we randomly select and individual that is a rancher and drinks beer is what? Answer in a fraction. c) the probability that we randomly select and individual that is a rancher and does not drink beer is what? Answer in a fraction.
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.
