The answer to this question explains why alot of police detective work begins with relatives and friends of the victim! About 64% of people who are murdered actually knew the personwho committed the murder (Source: Chances: Risk and Odds inEveryday Life, by James Burke).

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.
