Question

corrin needs to make a 2 character alphanumeric code staring with the numbers 0-9

Answer 1

To create a 2-character alphanumeric code starting with a number (0-9), the first character must be a digit from 0 to 9, and the second character can be any alphanumeric character (0-9, A-Z, or a-z).

Here's how to break it down:

1. **First Character:** Choose from the digits 0-9 (10 choices).
2. **Second Character:** Choose from the alphanumeric characters (0-9 gives 10 options, A-Z gives 26 options, a-z gives 26 options). This results in a total of 62 options (10 + 26 + 26).

**Total Combinations:**
- 10 choices for the first character (0-9)
- 62 choices for the second character (0-9, A-Z, a-z)

So, the total number of unique 2-character alphanumeric codes starting with a digit is:

\[
10 \text{ (choices for first character)} \times 62 \text{ (choices for second character)} = 620 \text{ possible codes.}
\]
