At a Raffle, 1000 tickets are sold at $5 each. There are 20 prizes of $100, and 1 grand prize of $2000. Suppose you buy one ticket. Let the random Variable X represent your net gain (remember that the net gain should include the cost of the ticket) after playing the game once. Question: Find the expected value of X, and interpret it in the context of the 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.
