Standard automobile license plates in a country display 2 numbers, followed by 2 letters, followed by 3 numbers. How many different standard plates are possible in this system? (Assume repetition of letters and numbers is allowed.)

Answer: 67,600,000 license plates

 

Explanation:

There are ten digits and 26 letters.

This is simply \(10 \times 10 \times 26 \times 26 \times 10 \times 10 \times 10\), or \(10^5 \times 26^2\).

This equals 67,600,000.

 

You are very welcome!
