There are 24 permutations with four digits, assuming no repetition:

These are as follows:
{1,2,3,9} {1,2,9,3} {1,3,2,9} {1,3,9,2}
{1,9,2,3} {1,9,3,2} {2,1,3,9} {2,1,9,3}
{2,3,1,9} {2,3,9,1} {2,9,1,3} {2,9,3,1}
{3,1,2,9} {3,1,9,2} {3,2,1,9} {3,2,9,1}
{3,9,1,2} {3,9,2,1} {9,1,2,3} {9,1,3,2}
{9,2,1,3} {9,2,3,1} {9,3,1,2} {9,3,2,1}

The formula to work out permutation without repetition is n! / (n - r)!.

If using numbers 0 through 9 how many different 4 digit combinations can be made?

To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations. Since repetition is allowed, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.


How many combinations for a 4 digit number?

A 4-digit number can range from 0000 to 9999, which includes all combinations of four digits. Since each digit can be any number from 0 to 9 (10 options), the total number of combinations is calculated as (10^4). Therefore, there are 10,000 different combinations for a 4-digit number.
