Using the Fundamental Counting Theorem, it is found that Kami could create 40,000 codes that start with an even number.
<h3>What is the Fundamental Counting Theorem?</h3>It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem:
- The first digit has to be even, that is, 2, 4, 6 or 8, hence
.
- For the remaining digits there are 10 outcomes for each.
Hence:
Kami could create 40,000 codes that start with an even number.
