COMBINA
Formulas / COMBINACount combinations with repetitions allowed.
COMBINA(number, number_chosen)
- number - required, must be greater than 0 and greater than or equal to number_chosen
- number_chosen - required, must not be less than 0
Examples
=COMBINA(10,3) returns 220In this example, the COMBINA function is used to calculate the number of possible combinations from a set of 10 items taken 3 at a time. The result is 220, because there are 220 distinct combinations of 3 items that can be taken from the set of 10.
=COMBINA(B6,C6)In this example, the COMBINA function is used to calculate the number of possible combinations from a set of items in column B. The number of items to be chosen is specified in the corresponding cell in column C. For example, if cell B6 contains the set {A, B, C, D} and cell C6 contains the number 2, the result of the COMBINA function will be 6, since there are 6 combinations of 2 items that can be taken from the set {A, B, C, D}.
Summary
The COMBINA function is used to calculate the number of combinations of items. It requires two arguments, number and number_chosen, which must be greater than or equal to 0.
- The COMBINA function requires two arguments: number and number_chosen.
- The number argument is the total number of items and the number_chosen argument is the number of items in each combination.
- The COMBINA function returns the number of combinations with repetitions allowed in a given set. To count combinations that do not have repetitions use COMBIN.
