## How many number combinations are possible with 5 numbers?

How many combinations of 5 numbers are there? The number of 5-digit combinations is 10 5=100,000. So, one more than 99,999. You can generalize that: the number of N-digit combinations is 10 N.

## How many 3 number combinations can 5 numbers make?

10 possible combinations

So 5 choose 3 = 10 possible combinations.

**How many 5 digit numbers can be made from the digits 1 to 7 if repetition is allowed?**

How many five-digit numbers can be made from the digits 1 to 7 if repetition is allowed? Explanation: 75 = 16807 ways of making the numbers consisting of five digits if repetition is allowed.

### How many combinations of 2 numbers are there?

So that means you need to know how many different permutations there are for each combination. If there are two numbers, there are two permutations per combination. Divide the possible permutations by number of permutations per combination: 2450 / 2 = 1225.

### How many combinations of 2 are there?

**How many number combinations can you make with 1, 2 and 4?**

There are a total of 24 number combinations that can be made using just the numbers 1, 2, 3 and 4. These 24 number combinations are listed below in order of number combinations, beginning with the number 1 and finishing with number combinations that begin with the number four.

#### How many 4 digit combinations are there with no repetitions?

If there are no repetitions, you have 6 choices for the highest (leftmost) digit, then 5 choices left for the next highest digits, then 4 choices left for the next highest digit, and, finally, 3 choices for the last remaining digit. This, the total number of choices is 6*4*5*3 = 6! / (6 – 4)!

#### How many 4 digit combinations are there in a sentence?

For each 4 digit combination there’s a 2 digits one with remaining digits. First digit has 6 choices. The second has 5. We have 30 combinations. Using permutations and the factorial method, the number of arrangements can be determined by finding the factorial for “n” number of words or numbers that are contained in a sentence or number series.

**How to generate a list of all possible 4 digits?**

In Excel, you can use below formula to list all possible 4 digits combinations of number 0 to 9. Select a blank cell and type this formula =TEXT (ROW (A1)-1,”0000″) into it, and press Enter key, then drag the autofill handle down until all the 4 digits combinations are listing.
