Probabilities of Death The US Social Security Administration collects information in the life expectancy and death rates of the population. The table below gives the number of US men out of 100,000 born alive who will survive to a given age, based on 2011 mortality rates.1 For example, 50,344 of 100,000 US males live to their 80th birthday.

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.
