Answer:
468,000 different codes
Step-by-step explanation:
The code has first 2 letters and then 3 numbers.
The first letter has 26 possibilities to be filled.
The second letter has 25 possibilities, as one letter is already used.
Then, for the numbers, we have:
The first number has 10 possibilities to be filled.
The second number has 9 possibilities to be filled (one used).
The third number has 8 possibilities to be filled (two used).
So, the total number of different codes is:
26*25*10*9*8 = 468,000 different codes.
