Combination nCr Formula

C ( n , r ) = ( n r ) = n ! ( r ! ( n r ) ! )

What is combination?

Calculate the possible combinations is a mathematical and statistical practice where we find out the possibilities of a particular sample called r value from the space that is called N, sometime refered as population. In combinations the order does not matters and repititions are not allowed. This is simply the arrangements of given objects in specific or can say possible orders. Combinations are also calculated in modern research and data analysis field. There is defined formula for the calculation of combination as C ( n , r ) = ( n r ) = n ! ( r ! ( n r ) ! )

Key parameters for combination calculation

There are two parameters required for the calculation of combinations N and r. Where N refers to as population size and r is used as sample size.
