There are different numbers of combinations for groups of different sizes out of 9: 1 combination of 9 digits 9 combinations of 1 digit and of 8 digits 36 combinations of 2 digits and of 7 digits 84 combinations of 3 digits and of 6 digits 126 combinations of 4 digits and of 5 digits 255 combinations in all.
Just one. In a combination, the order of the digits does not matter.
There are infinite combinations that can make 3879
Five-digit combinations of numbers from 0 to 9 can range from 00000 to 99999. Each digit can independently be any number from 0 to 9, leading to a total of 10 options per digit. Consequently, there are (10^5) or 100,000 possible combinations. Each combination can include repeated digits and leading zeros.
To create a combination of three-digit numbers from the digits 1 to 9 that yields the same sum, you can select different sets of three digits that add up to the same total. For example, the combinations (1, 2, 3) and (1, 4, 2) both sum to 6. You can then form three-digit numbers using these combinations, such as 123 and 132, which will still sum the same. The key is to ensure that the chosen digits in each combination always add up to the same total.

120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.
There are 167960 9 digits combinations between numbers 1 and 20.
Just one. In a combination, the order of the digits does not matter.
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.

There are 126 different 5 digit combinations. Note that the combination 12345 is the same as the combination 45312.
If you include the combination which comprises no numbers (the empty set), then there are 16: 1 with no digits 4 with 1 digit 6 with 2 digits 4 with 3 digits, and 1 with 4 digits.

If the 6 digits can be repeated, there are 1296 different combinations. If you cannot repeat digits in the combination there are 360 different combinations. * * * * * No. That is the number of PERMUTATIONS, not COMBINATIONS. If you have 6 different digits, you can make only 15 4-digit combinations from them.
To find the even two-digit numbers where the sum of the digits is 5, we need to consider the possible combinations of digits. The digits that sum up to 5 are (1,4) and (2,3). For the numbers to be even, the units digit must be 4, so the possible numbers are 14 and 34. Therefore, there are 2 even two-digit numbers where the sum of the digits is 5.
