Question 350950
The NY Dept of Motor Vehicles (DMV) designs its license plates with space for 7 letters or numerals. In the most recent iteration, the DMV uses 3 letters followed by 4 numbers. Since the first 3 spaces are always letters, assume that I and O are valid possibilities. How many different license plate numbers are possible? 
-------------------
# of possible plates = 24^3*10^4 = 138,240,000
