A thief steals an ATM card and must randomly guess the correct three-digit pin code from a 10-key keypad. Repetition of digits is allowed. What is The number of possible codes is (Type an integer or fraction. Simplify your answer.)

When creating a three-digit PIN code using a 10-key keypad (0 through 9), you have 10 options for each digit. Since repetition of digits is allowed, the total number of combinations can be calculated as: 10 (options for the first digit) × 10 (options for the second digit) × 10 (options for the third digit) = 1000 possible PIN codes. Thus, there are 1000 different potential combinations for the PIN code.
