Suppose you have the social network like in the following picture. The circles are people and the edges are interactions between people. Suppose the person in the centre gets a virus. In each interaction, there is a 4/5 probability of passing on the virus. a. What's the probability that only 1 person has the virus? b. What's the probability that only 2 people get the virus? c. What's the probability that only 3 people get the virus?

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.
