Solution
- n choose r. Gives the number of subsets of r elements , out of n elements. nCr = n ! r ! ( n − r )! = n ! r ! ( n − r )!
- Plug in n =9, r =6. =9! 6! (9−6)!
- 9! 6!( 9−6)! = 84. =84.

How do you evaluate nCr? How Do you Use NCR Formula in Probability? Combinations are a way to calculate the total number of outcomes of an event when the order of the outcomes does not matter. To calculate combinations we use the nCr formula: nCr = n! / r! * (n – r)!, where n = number of items, and r = number of items being chosen at a time.
