Hi there--
.
The counting principle say that we multiply the number of ways for each of these events together to get the total number of ways to get a license plate.
.
number of ways to get the 1st number (the digits 1 through9): 9 ways
number of ways to get the first letter: 26 ways
number of ways to get the next letter (repetitions OK): 26 ways
number of ways to get the third letter: 26 ways
number of ways to get the next number (0 is OK): 10 ways
number of ways to get the next number (repetitions OK): 10 ways
number of ways to get the next number: 10 ways
.
Total number of ways to get a license plate:

.
There are 158,184,000 ways to create a license plate in this system.

Hope this helps! Feel free to email me if the explanation is unclear.
