A bag contains 1 dime, 1 nickel, and 7 pennies. We will draw out 2 coins at random, and look at what we get. (Note that this is without replacement.) Let x be the random variable that represents the total value of the two coins drawn. List the possible values of x. Put them on the table at right. Find the probability of each value. Put them on the table at right. (If your probabilities do not add to 1, you have made a mistake.)
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.
