Best ResponseYou've already chosen the best response.1I don't think your factorial equation is right... follow this format \[\frac{ n! }{ k! (nk)! }\] and try simplifying now

Best ResponseYou've already chosen the best response.0On my notes it says nCk = n!/(nk)! k! so id rather do it that way :) but it would still be the same way right?

Best ResponseYou've already chosen the best response.1You would get 15!/ 15!. 10! that way and I don't think you should have a negative factorial

Best ResponseYou've already chosen the best response.0The way i simplified it was 15 14 13 12 11 10 _________________________ 10 5 4 3 2 1 I crossed out the 10's and then from there it doesnt seem right, but its the way my teacher taught us. so for ex, 5 *3 = 15 7*2 = 14

Best ResponseYou've already chosen the best response.0so then 3 would go on top of the 15 and the 7 would go on top of the 14
