When an adult over the age of 50 is selected, there is a 0.63 probability that they know what TikTok is. Suppose that we want to find the probability that exactly three of five randomly selectec adults know what TikTok is. a) Does this procedure yield a binomial distribution? If so, what is our binomial random variabler b) What is the value of n, k, p, and q?

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.
