You create a general AI (artificial intelligence) and want to teach him “friendship" as a relation on a set of people. You define some rules for this friendship relation. These are your four laws of robotic friendships: 1. "Everyone is friend of him or herself". 2. “Not everyone is friend with everyone". 3. "The enemy of my enemy is my friend" (here “enemy" just means “not friend"). 4. "The enemy of my friend is my enemy." a) Can the following directed graph represent the above "friendship" relation on a set of 2 people? Justify your answer.
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.

Can the above solution be made more clear. What does this mean? "So, B is enemy of B's friend and hence B is enemy of B." Since B is friends with B, B has to be an enemy of B's friend. But B is already an enemy of B's friend, which is A.
