Why do you waste our time by posting the same question twice?
It is against the forum rules you know.
There are 40 State employees
There are 20 Federal Employees

a) Let X be the number of State workers. Write the pmf of X.
HOW DO YOU WRITE A PMF/PDF. My teacher is a moron and doesn't teach. Can someone teach me how?
