A high-speed train makes a 600 mile nonstop run between two major cities in 7 1/2 hours. The train travels 100 mph in the country, but safety regulations require that it travel only 25 mph when passing through smaller, intermediate cities. How many hours are spent traveling through the smaller cities?
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.
