# How many combinations with 4 items?

I.e. there are 4 objects, so the total number of possible combinations that they can be arranged in is 4! = 4 x 3 x 2 x 1 = 24.

## Taking this into account how many combinations of 4 items have no repeats?

The number of possible combinations with 4 numbers without repetition is 15.## Given this circumstance, how many combinations can you have with 4 items?

If you meant to say "permutations", then you are probably asking the question "how many different ways can I arrange the order of four numbers?" The answer to this question (which you got right) is 24.## In the same manner people ask how many 4 digit combinations can 4 numbers make?

There are 10,000 combinations of four numbers when numbers are used multiple times in a combination. And there are 5,040 combinations of four numbers when numbers are used only once. How so? Well, there are 10 choices, zero through nine, for each number in the combination.## Do you have your own answer or clarification?
