You have a revolver that holds up to five bullets and a revolver that holds up to eight bullets. You simultaneously pull each gun’s trigger and then randomize the position of the bullets by spinning the cylinders. You repeat this until each gun fires at least one time. What is the expected number of trials for both guns to fire? Suppose instead that you simultaneously pull the triggers until a gun fires. Now, what is the expected number of trials?
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.
