+129852 Just n
We have n things and we want to choose just 1
n ways to do that !!!
+775 n choose 1 is always n. Similarly, n choose n and n choose 0 are always 1.
\({n}\choose{1}\) = n. \({n}\choose{n}\) = \({n}\choose{0}\) = 1.

+1252 That's just \(n\) !
Imagine you have 10 cakes in front of you and you choose one. How many possibilities are there? 10 possibilities, of course! (Unless you are like me and you love cake so you sneak another one 
) This is for any number, not just 10, of course.
You are very welcome!
:P
