Assuming you are using combinations in the colloquial way (which is the mathematical "permutations" where order of selection does matter) to create a 3 digit number that does not start with 0, ie creating a number that is between 100 and 999 inclusive then:

If repeats are not allowed there are 3 × 3 × 2 = 18 possible numbers

If repeats are allowed, then there are 3 × 4 × 4 = 48 possible numbers.

If you are using combinations in the mathematical sense where order of selection does not matter and are creating groups of 3 digits, then:

If repeats are not allowed there are 4 possible groups

If repeats are allowed there are 20 possible groups.

To calculate the number of 4-digit combinations you can get from the numbers 1, 2, 2, and 6, we need to consider that the number 2 is repeated. Therefore, the total number of combinations is calculated using the formula for permutations of a multiset, which is 4! / (2!1!1!) = 12. So, there are 12 unique 4-digit combinations that can be formed from the numbers 1, 2, 2, and 6.
