Suppose you run an accounting firm and you're concerned about gender discrimination in the hiring process. The hiring process at your firm consists of two stages: review of resumes and then an in-person interview. Imagine that for a particular position your firm gets 120 resumes, 40 of which are from women. Your company will select 20 resumes for the in-person interview. If very few women are selected for the interview stage, it might be due to random chance or it might be due to sexism. (Assume every applicant, regardless of gender, is equally qualified.) To inform you on which it is, you need to know the likelihood that it's due to random chance. Using the appropriate distribution function in Excel, determine the chance of zero women making it to the in-person stage. Express your answer as a decimal to four places. Include a zero before the decimal point.

In a large population, 55% of the people have been vaccinated. If 5 people are randomly vaccinated what is the probablility that at least one of them has been vaccinated?

he concept of probability, including the notion of an experiment, outcomes, and sample space. How can each of these be useful to us?

Given a bag of 10 marbles, 4 of them are white, 2 are black, and 4 are stripe. What is the probability of pulling a black marble, then a white marble, when sampling without replacement (i.e., you do not put the 1st marble back into the bag)?
