Question

if nc10=nc6 find 11c11. please answer me fast!!!

Answer 1

Answer:

nCr= n!/r!×(n-r)!

11c11=11!/11!×(11-11)!

=1/0!

=1. (0! =1

Answer 2

We will get answer as 1.

Step-by-step explanation:

In permutation and combination we have formula for combinations as

⇒C(n,r)= n!/r!(n-r)!

⇒P(n,r)=n!/(n-r)!

⇒Here ,in the question we are given ,to find the value of C(11,11)

So, putting the values in the equation

⇒C(11,11)=11!/11!(11-11)!

⇒We will get 11!/11!×0!

⇒which is equal to 1.
