A marksman takes 10 shots at a target and has probability 0.2 of hitting the target with each shot, independently of all other shots. Let ? be the number of hits. What is the probability of scoring no hits? Find the expectation and variance of ?.
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.
