Use Bayes Theorem to calculate the probabilities: The enrollment in a certain course is 10% first year students, 30% sophomores, 40% juniors and 20% seniors. Past experience has shown that the likelihood of receiving an A in the course is .2 for first year students, .4 for sophomores, .3 for juniors and .1 for seniors. Find the probability that a student who receives an A is a sophomore.
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.
