To calculate the number of possible combinations from 10 items, you can use the formula for combinations, which is nCr = n! / r!(n-r)!. In this case, n is the total number of items (10) and r is the number of items you are choosing in each combination (which can range from 1 to 10). So, if you are considering all possible combinations (r=1 to 10), the total number of combinations would be 2^10, which is 1024.
6 different combinations can be made with 3 items
If repeats are allowed than an infinite number of combinations is possible.
Do a web search for "permutations and combinations" to find the how. I make it 35,960.
There are 5C3 = 10 combinations.
There are 167960 combinations.
6 different combinations can be made with 3 items
If order doesn't matter, 15 combinations and if order does matter, 360 combinations are possible.
3 items each in 3 categories gives 3*3*3 = 27 possible combinations.
If repeats are allowed than an infinite number of combinations is possible.

There are 5C3 = 10 combinations.
If the numbers are allowed to repeat, then there are six to the fourth power possible combinations, or 1296. If they are not allowed to repeat then there are only 360 combinations.
There are millions of possible combinations.
2^n possible combinations
There are 2^5 = 32 different combinations of the five traits possible.
There is only one combination of ten items out of ten. For this question to have a non-trivial answer, either the ten items need to be selected from a larger number of items or a smaller number of items need to be selected from the ten items.
