Through the career services office, you have arranged preliminary interviews at four companies for summer jobs. Each company will either ask you to come to their site for a follow-up interview or not. Let X be the random variable equal to the total number of follow-up interviews that you might have.
a) List all the possible values of X.
b) Is the random variable discrete or continuous?
c) Do you think a uniform distribution might be appropriate as a model for this random variable? Explain briefly.
