Question

A company puts a code on each different product they sell. The code is made up of 2 numbers and 1 letter. How many different codes are possible?

• A. $46$
• B. $2600$
• C. $1300$
• D. $5200$

Answer 1

The correct option is B $2600$

There are 3 stages (number 1, number 2, letter 1).

There are 10 possible numbers: 0 – 9.

There are 26 possible letters: A – Z.

So we have:
$10\times 10\times 26=2600$ possible codes.
