Students were all given a test that they ALL guess on. It had 10 questions and each were true or false. What is the probability that someone scored 0 or 10%
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.

Given that Students were all given a test that they ALL guess on. It had 10 questions and each were true or false.
Let, x be the scores of test
p is probability of success
Since there are only two outcomes of the question true / false . It follows Binomial distribution with n = 10 trials (question)
& p = 0.5 .
