In a local college, 70% of students have a part-time job outside of school. Suppose that we want to find the probability that when we randomly choose 15 students exactly 8 of them have a part-time job outside of school. A) What would a “success” be in our case? What is our probability of success, p? B) What is our probability of failure, q? C) Find the probability that when we randomly choose 15 students exactly 8 of them have a part-time job outside of school. Round your final answer to two decimal places.
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.
