Question

Suppose each license plate in a certain state has one digit, followed by four letters, followed by one digit. The letters F, O, S, and X and the digit 0 are not
used. So, there are 22 letters and 9 digits that are used. Assume that the letters and digits can be repeated. How many license plates can be generated using
this format?

Answer 1

Each digit can be 1 of 9 numbers.

Each letter can be 1 of 22 letters.

To find total combinations, Multiply each number of choices by each number of choices.

9 x 22 x 22 x 22 x 22 x 9 = 18,974,736 total combinations
