WebYou have n objects, and you need to choose k of them. You can do that in ( n k) ways. Then for each choice of those k elements, we can permute them in k! ways. Using the multiplicative principle, we get another formula for : P ( n, k): . P ( n, k) = ( n k) ⋅ k!. 🔗 Now since we have a closed formula for P ( n, k) already, we can substitute that in: great yarmouth coach station
