A teacher will select a student from a class with N students to present their work. A random selection will be done to determine the order of each student. She wrote the names of all students on small pieces of paper and put the papers in an urn. Accidently, your name has been written twice. What is the probability that you will be selected in the nth placement for n = 1, 2, . . . ,N?
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.
A teacher will select a student from a class with N students to present their
