    C(6,4) is the notation we use to find the number of ways you can CHOOSE 4 from 6 items
if the order does not matter. This is called a combination.
C(n,r) = n!/(r!9n-r)!)
sometimes written as <sub>n</sub>C<sub>r</sub>
If you are getting these kind of questions, you MUST be familiar with this terminology.
