The number of possible 8 digit combinations of 0-9 is mathematically the number of unique sets of 8 numbers are selected from a group of 10 and order doesn't matter. This is expressed 10C8 and since this is the same number as choosing 2 numbers to be excluded, it is just 10 times 9 divided by 2. That makes 45 choices.

Sample Frequency. Change this to a number greater than 1 if you wish to see only every n combinations. Combination #1 will always be the first one shown. For example, setting this value to 3 will give you every 3rd combination in the results, so you will get combination 1, 4, 7, 10, and so on. Scrolling Output.

There are 90,000 different number combinations that can be made in a five-digit number if numbers can repeat. To determine the number of possibilities, each place digit has to be evaluated independently to see how many numbers could fit there and then all are multiplied together.

The first digit can take on nine values, from 1 to 9. For the second through fifth digits any number between 0 and 9 can be used. To find the total number of combinations, these values are then multiplied together: 9 x 10 x 10 x 10 x 10 = 90,000 total combinations. Learn more about Numbers.

Perhaps you meant the number of possible 8 digit combinations of 0-9 where order does matter. You still can't re-use digits though. We call these permutations. This is expressed 10P8 and is just 10 times 9: 90 choices.

If using numbers 0 through 9 how many different 2 digit combinations can be made? If there are no restrictions on duplicated numbers or other patterns of numbers then there are 10 ways of selecting the first digit and also 10 ways of selecting the second di…git. The number of combinations is therefore 10 x 10 = 100.
