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.
