Modeling and Simulation (Geometric Distribution) Q1) At Colombia University, each student has a probability of 0.8 to pass the simulation exam. Denote by X the random variable that represents the number of times a student must take the simulation exam in order to pass it (assume independent outcomes for each trial, and that probability of success remains the same). a) What is the average number of times a student has to take the exam?
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.

Random variables are of 2 types, discrete and continuous. Based on this classification of random variables, probability distributions are also of 2 typed, discrete and continuous.
Geometric distribution is a discrete probability distribution. The probability mass function of the geometric distribution is given below.
