A bag contains a coin and two dice. One of them is drawn from the bag at random (with equal chance) and tossed. We win $480 if we get heads, lose $12 if we get tails, win $36 if we get 6, and neither lose nor win for any other outcome. What is our expected gain if we play this game once? Enter an exact value without any units.

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.
