Suppose you toss a coin and will win $3 if it comes up heads. If it comes up tails, you toss again. This time you will receive $6 if it comes up heads. If it comes up tails, toss again. This time you will receive $12 if it is heads and nothing if it comes up tails. What is the mathematical expectation for this game?
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.
