Passing stats Molly’s college offers two sections ofStatistics 101. From what she has heard about the twoprofessors listed, Molly estimates that her chances ofpassing the course are 0.80 if she gets Professor Scedasticand 0.60 if she gets Professor Kurtosis. The registrar usesa lottery to randomly assign the 120 enrolled studentsbased on the number of available seats in each class.There are 70 seats in Professor Scedastic’s class and 50 inProfessor Kurtosis’s class.a) What’s the probability that Molly will pass Statistics?b) At the end of the semester, we find out that Mollyfailed. What’s the probability that she got ProfessorKurtosis?
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.
