Teo has a combination of quarters, loonies, and toonies in his pocket. He knows he has 9 coins in total and that he has at least one of each type of coin. a) What is the probability that Teo has more than $8? b) How many different combinations of coins could Teo use to pay for an item that costs between $10 and $12, if he uses fewer toonies than loonies?
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.
