Bill Dorfman is a champion shooting marksman with the Canadian Armed Forces. From 100 yards he can hit the center bullseye 92% of the time. In his upcoming competition he will be required to take 7 shots at the 100-yard range. a) Is this a uniform, binomial, or hypergeometric distribution? Explain? b) What does the random variable represent? What is/are the value(s) it can take? c) Calculate the probability that he won't hit the bullseye in all 7 shots.

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.
