A bag initially contains one red ball and two blue balls. An experiment consists of selecting a ball at random, noting its color and replacing it together with an additional ball of the same color. If three such trials are made, then find probability for following cases 1. exactly one blue ball is drawn. 2. All drawn balls are red given that all the drawn balls are of the same color. 3. At least one red ball is drawn.
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.
