Part 2 focuses on counting techniques and probability.

A student – faculty government committee of 4 people is to be formed from 20 student volunteers and 5 faculty volunteers.

a. If one person from the group of volunteers is chosen at random to draw the names out of a hat, what is the probability that the person drawing the names is a student?

d. How many ways can 2 faculty be chosen?

e. What is the probability that the random selection of the four- person committee will result in two students and two faculty
