@Pepsigurl alot of guys want to be just friends with girls.
Let's say.....
-
@Concrete_Angel I can never seem to get the hang of combinatorics. Are there some rules that im missing out?
-
@bunyonb I wouldn't know if u were missing out rules without knowing your working towards the problem and also I'm not overly familiar with the subject myself haha
-
@Concrete_Angel awww ok
-
@bunyonb oh I feel quite embarrassed haha as I have just realised that I misread the question 🙈 I read it as 4 men not 3 so my working is based on there being 6 people not 5.
5! - (4! × 2) = 120 - 48 = 72
So there are actually 72 combinations, a big difference to my first answer! Sorry about that haha
-
@Concrete_Angel lol np
-
This guy is a computer scientist and it he has a amazing mind
-
@GirlNextDoor Who?
-
It also can be done with permutations.
Personally i think it's easier to make 5P5 - (4P4 x 2) = 120 - 48 = 72 also -
@davitchen Wow that's great man.
-
@bunyonb Well thanks, have you been studying, or is it just curiosity?
-
@davitchen Studying. I need to understand it and other similar problems for exam prep.
-
@bunyonb Im also doing exam in the next week :) I'll have to repeat. So it was helpful that post ahahaha
-
@davitchen You are welcome lol
-
You need to learn to use factorials
-
@Concrete_Angel well looks like we have a genius here.
-
I don't know anything about any of these formulae, but I make it 72.
