A bag contains R red balls and W white balls. Each time you take one ball out of the bag at random and without replacement. You stop as soon as all red balls have been taken out of the bag. What is the expected number of white balls remaining in the bag when you stop?
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.
