A bag contains some white balls. On each ball a number is painted. The number painted on it runs from 1 to N. Suppose, there are k balls with number k. Now an experiment is conducted of choosing a ball at random, noting the number on it and returning to the bag. If the experiment is repeated N times. What is the average value of the number painted on the ball ?
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.
A bag contains some white balls. On each ball a number is painted. The number
painted on it runs from 1 to N. Suppose, there are k balls with number k. Now an
experiment is conducted of choosing a ball at random, noting the number on it and returning to the bag. If the experiment is repeated N times. What is the average
value of the number painted on the ball ?
