Is nPr and nCr same?
Permutation (nPr) is the way of arranging the elements of a group or a set in an order. The formula to find permutations is: nPr = n!/(n-r)! Combination (nCr) is the selection of elements from a group or a set, where order of the elements does not matter.
What is nPr and nCr in math?
In mathematics, nPr is the permutation of arrangement of ‘r’ objects from a set of ‘n’ objects, into an order or sequence. The formula to find permutation is: nPr = (n!) / (n-r)! Combination, nCr, is the selection of r objects from a set of n objects, such that order of objects does not matter.
