Assume that a fair six-sided die is rolled 14 times, and the roll is called a success if the result is in {1,2,3}. What is the probability that there are exactly 3 successes or exactly 3 failures in the 14 rolls? (Answer is not 91/4096)
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.
