Question

$Howdoyoucalculatecombinations?$

Answer 1

Calculation of combination:

Combinations are a way to calculate the total number of outcomes in an

event where the order of results does not matter.

To calculate combinations, we will use the formula $\mathit{n}\mathit{C}\mathit{r}\mathbf{=}\mathit{n}\mathbf{!}\mathbf{/}\mathit{r}\mathbf{!}\mathbf{*}\left(n-r\right)\mathbf{!}\mathbf{,}$

where $n$ represents the total number of items,

and $r$ represents the number of items at a given time.
