Web7. apr 2024 · Class 11 permutation and combination solutions: As per the question, n = 14 r = 3 By deriving the permutation formula- nPr = (n!) / (n-r)! = 14! / (14 - 3)! = 14! / 11! = (14 X 13 X 12 X 11!) / 11! = 2184 Now, from the combination formula- nCr = (n r) = nPr / r! = n! / {r! (n-r)!} = 14! / 3! (14 - 3)! = 14! / 3! (11!) = 14 X 13 X 12 X 11! / 2!
