Quizplus · Accepted Answer

For a 3-digit code using the digits 0 through 4 with no repetitions allowed, the first digit can be any of the 5 options (0-4), the second digit can then be any of the remaining 4 options (since one digit was used for the first position), and the third digit can be any of the remaining 3 options. Therefore, the total number of possible codes is 5 * 4 * 3 = 60.
