A series of specialty license plates consists of three digits followed by two letters. How many unique license plates are possible?

There are only twenty four letters your can use (can 't have 1 or 0 as they look like 1 and 0) therefore the number of combinations is 10 * 10x 10 x 24x24x24x=13824000 so therefore 10 different possible digits and 26 different possible letters
