1. According to the stated question, the conditions are:

The (serial) numbers are produced by two (distinct) letters ("two of these letters") followed by (any) two digits (0-9), then the number of ways products can be numbered will be:

first letter : 10 ways
second letter: 9 ways
first digit: 10 ways
second digit : 10 ways
Total=10*9*10*10=9000 ways.

If the two digits are to be distinct (which has not been specified), then there are 9 ways for the second digit and the total is 8100.
