There are 26 possibilities for the first two characters of the password. So that part has 26 * 26 possibilities.


There are 10 digits, 0-9. The first character that's a digit has 10 possibilities, the second has 9 (they cannot repeat), and the third has 8.


The total number of possible passwords is 26*26*10*9*8 = 486720
