Question

In Utah, a license plate consists of 3 digits followed by 3 letters. The letters I, O, and Q are not used, and each digit or letter may be used more than once. How many different license plates are possible?

Answer 1

I am assuming that the zero can be used in any of the 3 opening places.

e.g. 000ABC should be ok and we can only use 23 of the 26 letters.

so 10x10x10x23x23x23 = 12167000
