1.) In a sample of 250 students travelling to campus, 190 use taxis. Of the taxi commuters, 130 travel more than 15km. Of those who do not use taxis, 40 travel less than 15km. Compile a contingency table and answer the following question. What is the probability that a student from the sample travels more than 15km given that the student use taxis?
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.
