How many different license plates can be made using 2 letters followed by 3 numbers?

OpenStudy (anonymous):

without repetition i guess

OpenStudy (anonymous):

\[26\times26\times10\times10\times10=676000\]

OpenStudy (anonymous):

Without repitition 26*25*10*9*8*7 = 468000 each time with one less letter/number because you can't use it again

OpenStudy (anonymous):

Why can't a number/letter be used more than once in a number plate?

OpenStudy (anonymous):

I don't know, I was going by the first reply

OpenStudy (anonymous):

Fair enough.
