You can put this solution on YOUR website! A license plate is to consist of two letters followed by three digits. How many different license plates are possible if the first letter must be a vowel, and repetition of letters is not permitted, but repetition of digits is permitted?
-------------------------------------
# of ways to pick 1st letter: 5
# of ways to pick 2nd letter: 25
# of ways to pick 3 digits: 10^3
-------------------------------------
Total # of license plates: 5*25*1,000 = 125,000
