Financial PINs are often four-digit numbers in the range 0000–9999, resulting in 10,000 possible combinations.

The first digit cannot be 0. Therefore, we have 9 choices (1 to 9) for the first digit, and 10 choices (0 to 9) for each of the other 3 digits. Therefore, 9 * 10 *10 * 10 = 9000 4-digit numbers are possible.

What are the total amount of choices possible if an individual is to create a 4-digit password using the digits 0 through?

There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code.

What are the total amount of choice is possible if an individual is to create a four-digit password using the digits zero through nine inclusive?

So there are 10,000 possible 4-digit combinations using the digits 0–9.

How many four digit personal identification numbers like those used with debit cards are possible if zero Cannot be used as the first digit and no digit may be repeated?

How many PINs are possible if no digits can be repeated?

What is the probability that there are no repeated digits? There are 10 possible values for each digit of the PIN (namely: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9), so there are 10 · 10 · 10 · 10 = 104 = 10000 total possible PIN numbers.

What is the probability of me guessing your 4 digit PIN number if I know that none of the numbers are repeated?

To have no repeated digits, all four digits would have to be different, which is selecting without replacement. We could either compute 10 · 9 · 8 · 7, or notice that this is the same as the permutation 10P4 = 5040. Hence, there is a 50.4% chance that the 4-digit PIN has no repeated digits.
