COMBINATIONS (Array,HowMany)

This function shows the combination of the given numbers.
A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected.
In $COMBINATIONS(Array,HowMany)$ , $Array$ is the set of numbers and $Howmany$ is the described number of choice.
The number of ways of picking k unordered outcomes from n possibilities.
Also known as the binomial coefficient or choice number and read "n choose k," ${\binom {n}{k}}={\binom {n-1}{k-1}}+{\binom {n-1}{k}}$ nck= Formula.
Here COMBINATIONS shows the choices of the selected objects.
