Question 874151: what are the total amount of choices possible if an individual is to create a 4 digit password using the digits 0-9 inclusive but not using the digit 0 as the first character of the password

Each password is of the form ABCD

9 choices for slot A (1-9)
10 choices for slot B (0-9)
10 choices for slot C (0-9)
10 choices for slot D (0-9)

Multiply out the number of choices: 9*10*10*10 = 9000

If repeats are allowed, then there are 9000 different passwords.
