Each license plate in the Flat Land must have exactly three characters, two of which are two different digits from 0 to 9 and one of which is a capital letter from to Z. Find the number of possible license plates.

letters = 26

numbers = 10 C 2 =  10!/(8!2!) = 45 choices    BUT they can be in three different positions

 

26 * 45 * 3 = __________ combos
