b. Let z equal the number of students who receive an offer. Is æ continuous or discrete?
It is discrete
c. Show the value of the random variable z for each of the experimental outcomes, where z is the number of yeses. Y = "Yes, the student receives an offer", and N = "No, the student
does not receive an offer." If your answer is zero, enter "0".
