Given a set X with n elements and positive integer r then r-permutation of n elements is defined by

Answer:
What does the N and R mean in permutations?
n = total items in the set; r = items taken for the permutation; "!" denotes factorial. The generalized expression of the formula is, "How many ways can you arrange 'r' from a set of 'n' if the order matters?" A permutation can be calculated by hand as well, where all the possible permutations are written out.
What is N and R in combination?
One could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n! (n−r)! n! is read n factorial and means all numbers from 1 to n multiplied e.g.
What is a combination of r elements of a set?
An r-combination of elements of a set is a subset with r elements. . These numbers are referred to as binomial coefficients.
What is N in permutation formula?
If the order doesn't matter then we have a combination, if the order does matter then we have a permutation. One could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n!
