Step 1

The first step is to define the fundamental principle of counting. The fundamental principle of counting states that if a process can be carried out in n steps, where there are  ways to complete the first step, ways to complete the second step, , and ways to complete the step, this process can be carried out in   ways.

Step 2

We use the fundamental principle of counting with for a total of steps.  This test can be carried out in ways. This comes from multiplying 4 by itself 16 times.
