0-10 mph over limit 10-20 mph over limit More than 20 mph over limit Total Male 9 9 17 35 Female 2 9 4 15 Total 11 18 21 50 f) If a random ticket was selected, what would be the probability that the driver is a female or driving 0-10 mph over the limit?
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.
0-10 mph over limit | 10-20 mph over limit | More than 20 mph over limit | Total | |
