- Homework Statement
- If n is an even natural number, then the greatest value of nCr is nCn/2 and if n is odd, then the greatest value of nCr is nC(n+1)/2 and nC(n-1)/2

- Homework Equations
- nCr=n!/(n-r)!r!

I know nCn/2 = n!/((n/2)!)^2 = 2^(n/2)(1.3.5.....n-1)

but I am not getting why it's the least one.
