**How to calculate the number of combinations at a time?**

The number of combinations of n distinct objects, taken r at a time is: n C r = n! / r! (n – r)! Thus, 27,405 different groupings of 4 players are possible. To solve this problem using the Combination and Permutation Calculator, do the following: Choose “Count combinations” as the analytical goal.

#### How to find all possible combinations of letters and numbers?

C ( n, r) = ( n r) = n! ( r! ( n − r)!) =? The Combinations Calculator will find the number of possible combinations that can be obtained by taking a sample of items from a larger set. Basically, it shows how many different possible subsets can be made from the larger set.

**How many possible combinations can you make with one element?**

If you choose only one element r = 1 at once from that set, the number of combinations will be 12 – because there are 12 different balls. However, if you choose r = 12 elements, there’ll be only 1 possible combination that includes every ball. Try it by yourself with the n choose r calculator!
