The percentage distribution of the number of occupants in vehicles crossing the Tacoma Narrows Bridge in Washington is shown in the pie chart. Find each probability. (Source: Washington State Department of Transportation.) (a) Randomly selecting a car with two occupants (b) randomly selecting a car with two or more occupants (c) Randomly selecting a car with between two and five occupants, inclusive One = 55.5% Two = 29.8% Three = 7.6% Four = 4.7% Five = 1.4% Six or more = 1%
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.
