You study for an exam, but due to the fact that you waited too long, you only learn 40% of the material. The exam is all multiple choice, with each question having 5 choices. a) If you come across a question for which you don't know the answer, what's the probability of getting the answer right? b) If you come across a question for which you do know the answer, what's the probability of getting it right (hint: don't “over think” this - what does it mean if you know the answer...)? c) What is the overall probability of getting any question correct?
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.
