If you must use each digit once, and only once, then there are 3 ways to pick the first digit, and 2 way to pick the second. This then leaves only 1 number available for third place, so there is no choice for it. 3 multiplied by 2, multiplied by 1 = 6

123

132

213

231

312

321

If you don't have to use each digit very time, but still cannot repeat a digit then there are 9 extra choices available. 012

How many 3 digit combinations are there in the numbers 1 to 9?

It depends. If you can only use each number once, there are 720 combinations. If you can use numbers multiple times, then there are 1000 combinations, by using all numbers from 000 to 999.


How many 5 digit combos in 30 numbers?

The answer will depend on how many digits there are in each of the 30 numbers. If the 30 numbers are all 6-digit numbers then the answer is NONE! If the 30 numbers are the first 30 counting numbers then there are 126 combinations of five 1-digit numbers, 1764 combinations of three 1-digit numbers and one 2-digit number, and 1710 combinations of one 1-digit number and two 2-digit numbers. That makes a total of 3600 5-digit combinations.


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 the numbers one two and three using each digit only once can I get?

6 - 123, 132, 213, 231, 312, and 321.


If using numbers 0 through 9 how many different 4 digit combinations can be made with no restrictions on order or repeats?

In other words, how many 4 digit combination locks are there using the digits 0-9 on each wheel. There are 10×10×10×10 = 10⁴ = 10,000 such combinations.

How many 6 digit combinations are there in 20 numbers?

Oh, what a lovely question! Let's paint a happy little picture here. To find the number of 6-digit combinations using 20 numbers, we can use a simple formula: 20P6, which stands for 20 permutations taken 6 at a time. This gives us 387,600 unique combinations to explore and create beautiful patterns with. Just imagine all the possibilities waiting to be discovered!
