This is a new function introduced in Excel 2013. This function is used to return the number of combinations with repetitions for a given number of items. The syntax of the Combina method is as follows: =COMBINA(number,number_chosen). In this way the Combina function takes two arguments; one is a number which should be greater than or equal to 0 and the other is number_chosen which should be also be greater than or equal to 0. For example: =combina(6,7) returns the number of combinations with repetitions for 6 and 7 i.e. 792.
