In a lottery game, a player will pick at random a number from the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. If the number picked is prime, the player wins P10. If the number picked is composite the player losses P10. If the number picked is 1 which is neither prime or composite, the player neither loss nor win anything. Let the random variable W have the values 0, -10, & 10 representing the possible winnings of the player. Solve for E(W). Show your solution.
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.
