dents in a faculty study in A department, 30% in B department and the rest in C department. The average of 10% of those studying in A section, 15% of those studying in B section and 20% of those studying in C section is above 3.00. When it is known that the average of a student randomly selected from these departments is above 3.00, what is the probability that the student is studying in department A?
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.
20% of the students in a faculty study in A department, 30% in B department and the rest in C department. The average of 10% of those studying in A section, 15% of those studying in B section and 20% of those studying in C section is above 3.00. When it is known that the average of a student randomly selected from these departments is above 3.00, what is the probability that the student is studying in department A?
