What is the formula of nCr and nPr?
In Maths, nPr and nCr are the probability functions that represent permutations and combinations. The formula to find nPr and nCr is: nPr = n!/(n-r)! nCr = n!/[r!
What is nCr formula in probability?
In probability, nCr states the selection of ‘r’ elements from a group or set of ‘n’ elements, such that the order of elements does not matter. The formula to find combinations of elements is: nCr = n!/[r!( n-r)!]
