You can put this solution on YOUR website! You have 3 letters and 3 numbers you can use. Thats a total of 6 choices
In the first position, you have 6 choices.
Since you can use repeats, in the second position you also have 6 choices.
so, 6 options for position 1 and 6 for position 2.
You have 36 combinations you can make ... just like if you had 2 dice !
