A license plate comprised of 3 letters followed by 3 numbers is to be chosen (repetition is allowed). If the first letter cannot be a "Z", how many different ways can this occur? In your answer, include the set up and calculations for the license plate.

Answer 1

$25\cdot26\cdot26\cdot10\cdot10\cdot10=16,900,000$

25(26)26(10)10(10)

16,900,000
