WebThe no. of permutations of n different objects taken r at a time, where 0 < r β€ n and the objects do not repeat is: n (n β 1) (n β 2) (n β 3) . . . (n β r + 1). β nPr = n ( n β 1) ( n β 2)( n β 3). . . ( n β r + 1) Multiplying and divided by (n β r) (n β r β 1) . . . 3 Γ 2 Γ 1, we get WebThe number of distinct combinations of n n objects, taken r r at a time, is determined by the formula C (n,r) = P (n,r) r! = n! r! Γ (n β r)! C ( n, r) = P ( n, r) r! = n! r! Γ ( n β r)! What is Permutation & Combination?
