An MBA graduate is applying for nine jobs, and believes that she has in each of the nine cases a constant and independent 0.48 probability of getting an offer. a. What is the probability that she will have at least three offers? b. If she wants to be 95% confident of having at least three offers, how many more jobs should she apply for? (Assume each of these additional appli- cations will also have the same probability of success.) c. If there are no more than the original nine jobs that she can apply for, what value of probability of success would give her 95% confidence of at least three offers?
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.

b. If she wants to be 95% confident of having at least three offers, how many
more jobs should she apply for? (Assume each of these additional appli-

c. If there are no more than the original nine jobs that she can apply for,
what value of probability of success would give her 95% confidence of at
least three offers?
