Suppose that a researcher goes to a small college with 200 faculty, 12 of whom have blood type O-negative. She obtains a simple random sample of n = 20 of the faculty and finds that three of the faculty have blood type O-negative. Is this experiment a hypergeometric probability experiment? List the possible values of the random variable X, the number of faculty that have blood type O-negative.

Approach Determine if the three criteria for a hypergeometric experiment have been satisfied.
