You may use Binomial. It could also be useful to look at the AddOn package
DiscreteMath`Combinatorica`, where you will find a wealth of interesting
things related to that.

In[1]:=
Binomial[6,2]
Out[1]=
15

Hello,

can I have mathematica solver things like a(over)b, (in how many ways 
can you pick "b" items from "a" items)?

I have mathematica 4.

Regards
Stefan
