**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*.
