(1) Find the number of choices for each character on the license plate.

1st of the 5 letters (any of the 26 except I or O): 24
2nd letter (any except I, O, or the 1st letter): 23
3rd letter (...): ___
4th letter: ___
5th letter: ___
1st digit (any of the 10 except 0): 9
2nd digit (any): 10

(2) By the fundamental counting principle, the number of license plates is the product of the numbers of choices for each character.

You can do the arithmetic (might need a calculator...)
