Question

Evaluate C(n, n). 0 1 n

Answer 1

Answer:

C(n,n)=1

Step-by-step explanation:

C(n,n) means we have to find the combination when n objects are to be selected from n objects.

Formula for C(n,r) is

$\dfrac{factorial\ n}{factorial\ r\times factorial\ (n-r)}$

Here, r=n

C(n,n) is equal to

$\dfrac{factorial\ n}{factorial\ n\times factorial\ (n-n)}$

$\dfrac{factorial\ n}{factorial\ n\times factorial\ (0)}$

since, factorial 0=1

Hence, C(n,n)=1
