A safe is randomly assigned a four-digit code. The company selling the safe sponsors a contest whereby contestants pick four digits (0 through 9) to make a 4-digit code. If the code opens the safe, the contestant wins $100. Otherwise, the contestant wins nothing. Let X be the random variable defined by the amount of money a contestant wins by picking one code. How many distinct values of X are there?
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.
