Assuming all 26 letters are used, and the first and last are digits, i.e. NAN, where N=digits 0-9, A=letter A-Z, there are, using the multiplication principle, 10*26*10=2600 distinct part numbers.
What is the minimum number of parts with the same serial number when there are 5000 parts and 2600 numbers available?
