Explanation

List the number of possible options for each character in the password. There are 10 possibilities for the first digit, 9 left for the second, and 8 left for the third. There are 26 possibilities for the first letter and 25 for the second. There are 10 × 9 × 8 × 26 × 25 = 468,000 possible passwords.
