While you are having coffee and some breakfast you notice that on the newspaper it says that one in 400 people are serial killers. Now you wonder, what are the odds that your waiter, or anyone in the diner for that matter, is a serial killer. You do a couple of quick back of the envelope calculations on a napkin. There are 13 people in the diner you’re having breakfast, excluding you. What is the probability that at least one of them is a serial killer?
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.
