I need some help with this question:
If a license plate for a vehicle consist of five characters: $4$ digits (the first of
which cannot be $0$), followed by one letter of the alphabet (which
cannot be $I$ or $O$), how many different license plates are possible?

We have a license plate format:
Using the rule of the product, that gives us:
$$9 \times 10 \times 10 \times 10 \times 24 = 9 \times 10^3 \times 24 = 216,000\;\text{license plates available}$$
