Solution

A combination is a set of ordered things and no matter what order is' it helps to find the number of possible combinations that

can be obtained by taking a subset of items from a larger set.

"crn" represents the combination formula

To calculate combinations we use the"crn" formula:

crn=n!/r!*(n-r)!,

where n=numberofitems

and r=numberofitemsbeingchosenatatime.
