Assume events are independent Suppose that for each individual selected, the probability that the individual has a certain flu that is going around is 0.42. (not having this flu is 0.58) Today I have come across 5 individuals (at random). We assume each has this same probability 0.42 of having the flu, and that each of these events are independent.
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.

Today I have come across 5 individuals (at random).
We assume each has this same probability 0.42 of having the flu, and that each of these events are independent.
Find the following probabilities
Find the probability that all 5 have the flu.
Find the probability that none of these 5 have the flu.
Find the probability that at least one the 5 individuals I met has this flu.
