1. A random experiment consists of throwing 4 equal coins, if X is the number of tails: a. Find the probability distribution of X and plot your graph b. What is the most likely tail number? Which one is the least likely? c. What is the average number of tails that come out, when throwing the four coins? d. What is the dispersion of X?
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.
