9. Incorrect. The answer is true not false. There are two classical ways of getting probabilities that involve counting. One involves knowing about the population, which the Schaum's Outline calls an a priori approach. If an event such as choosing 'Gold' can occur in h ways out of n possibilities, all of which are equally likely, then the probability of the event is h/n. In this example, there are two gold samples so h = 2 and there are 5 possible metals so n = 5. The second way is a sampling approach, which the Schaum's Outline calls an a posteriori approach or a frequency approach. If after n repetitions of a sampling process with replacement, where n is a very large number, an event happens h times, then the probability of the event is h/n. This fraction is usually called the empirical probability of an event.
