I waited for a week if anyone could reply you. 😢 I will pin their comments and give rewards, love react, to those who help others. ❤ Try this way. If this question 17.c) matches with your book. Solution. i) ⁿCr = C(n,r) This is a formula. Property of Combination. We can represent it by writing in both form. Solving L.H.S. Let, n = 4 objects. For r = 1 time C(4,1) press this in calculator we get = 4 For r = 2 time C(4,2) we get = 6. For r = 3 time C(4,3) we get = 4. For r = 4 time C(4,4) we get = 1. Now R.H.S. For n = 4, r = 1, = 4! / (4-1)! ×1! = 4! / 3! = 4 For n = 4, r = 2, = 4! / (4-2)! ×2! = 4! / 2!×2! = 6 For n = 4, r = 3, = 4! / (4-3)! ×3! = 4! / 3! = 4 For n = 4, r = 4. = 4! / (4-4)! × 4! = 4! /0! = 1 So, L.H.S. = R.H.S. for all experiments results. Hence Proved.
