There are 56 first year, 48 second year, and 32 third year students in a department. After the final examination, it is found that 3 of the first year, 10 of the second year, and 5 of the third year performed excellent and got a grade of 1.00 for the subject. If a student is chosen at random from this class and is found to have earned an A, what is the probability that he or she is a second year student? (Round your answers to two decimal places)
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.
