# How many combinations of 6 numbers are there with repeats?

## How many combinations of 6 numbers are there with repeats?

If you are just using the digits from 1 to 6, the answer would be 6*5*4*3*2*1 = 720, because you have 6 choices for the units digit, and then 5 choices left for the tens, and then 4 choices left for the hundreds and so on.

**How many combinations are in a 6 digit combination?**

1 million possible combos

But with a six digit code, there are 1 million possible combos, making it a lot tougher for someone to crack your security code. If you are currently using a four digit PIN and update your software, you will need to manually opt in for the six digit PIN.

**How many pairs can you make with 6 items?**

That means each item has 2 possibilities for every combination. For 6 items, that would make the number of combinations = 2^6 = 64.

### How many combinations can be made with 1 to 9 numbers?

Using the digits 1 to 9, with none repeating, 60,480 combinations can be made. To determine the number of combinations, find the number of digits possible for each position and then multiply these numbers. For example, using only numbers 1 to 6 would give the equation 6 x 5 x 4 x 3 x 2 x 1 (also known as 6! or 6 factorial) for a result of 720.

**How many ways can you choose 6 distinct numbers between 1-49?**

I *think* you are asking for the number of ways to choose 6 distinct numbers between 1 and 49 (inclusive), regardless of order. So the number of ways of picking an *ordered* sequence of numbers in the desired range is 49 x 48 x 47 x 46 x 45 x 44. But we only care about unordered sets of six numbers, not a sequence.

**How many possible combinations can you make with 12 different balls?**

If you choose only one element r = 1 at once from that set, the number of combinations will be 12 – because there are 12 different balls. However, if you choose r = 12 elements, there’ll be only 1 possible combination that includes every ball. Try it by yourself with the n choose r calculator!

#### How do you calculate the number of combinations in a group?

So the number of combinations is equal to the number of permutations divided by the size of the groups (which in this case is 6). The group size can be calculated by permuting over the number of chairs which is equal to the factorial of the number of chairs (k!).
