Do you know the formula for what C(n,k) is?

n!/((n-r)!r!)
n=13
r=4
=715
n=7
r=4
=35
n=6
r=4
=15

n is the pool or what you are choosing from and k is the select or the amount you can take

(715)-(525)/(715)

Looks correct to me. Now you just simplify that as much as you can.

yeah but when i do i get the wrong answer :[

i thought i could take the compliment... did i do it right?

And that should be a C(6,4) not a C(7,3). Sorry about that...

ok thank you!!!
