A box contains 8 balls. Two are numbered 3, four are numbered 4, one is numbered 5, and one is numbered 6. The balls are mixed and one is selected at random. The random variable X is the number of the ball. Find the probability distribution for X and calculate the mean. What is the probability that the number of the ball is greater than 3?
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.
