Multiplication principle for events: If one event can occur in p different ways, and another independent event can occur in q different ways, then there are pq ways that both events can occur together.

Example 1

How many different ways can a man coordinate a wardrobe if he has a choice of four different pants and two different sport jackets?

The first event (selecting pants) can occur in four different ways. The second event (selecting a sport jacket) can occur in two ways. Therefore, according to the multiplication principle for events, there are (4)(2) = 8 different ways to select a wardrobe.
