2. The Computer Systems Department has eight faculty, six of whom are tenured. Dr. Vonder, the chair, wants to establish a committee of three department faculty members to review the curriculum. If she selects the committee at random:
a. What is the probability all members of the committee are tenured?
b. What is the probability that at least one member is not tenured? (Hint: For this question, use the complement rule.)

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
a. Without replacement: 6/8 * 5/7 * 4/6 = ?
b. You want probability of one or both being chosen. Eitheror probabilities are found by adding the individual probabilities.
P(one) = 2/8 * 6/7 * 5/6 = ?
P (two) = 2/8 * 1/7 * 6/6 = ?
