Last February 200 students registered for the Undergrad course on the fundamentals of Probability Theory in the ECE department of the Venus University. In order to accommodate such a huge number of students, the departmental academic office decided to make 4 sections (A, B, C and D) with 50 students in cach section. Based on the official result announcenent from the Exam department, a total of 15 students secured a 4 GPA in the course. A Section-wise detail of those top GPA achievers in the Probability Theory course are given below. BCD 456 Section Number of students with 4GPA A student has been randomly selected (oquiprobable) from the batch of 200 students, now you have to determine the probabilities of the following events: a) The selected student was from Section-D. b) The selected student secured a 4 GPA in the course. c) The selected student secured a 4 GPA in the course and he'she was registered in Section- B. d) The student was registered in Section-A given that he/she secured a 4 GPA in the course

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.
