[paddydbarry]

Can someone please scan the paper in?

3 is C guys, it didnt ask for how many combinations, it just asked for a 6 at least once.

I still don't see how it's C. It is asking for amount of combinations.

 

[paddydbarry]

Could anyone who brought the paper home, scan in the multi choice for others to view?

Was the answer to question 3 C or D?

 

[idriss1]

Sorry, I was thinking of the dice question. The answer was C because 5,4 and 4,5 are counted as the same arent they? so you half it (i think)
the 5 being the 5th person and 4 being the 4th that is.

I wasn't sure if you just do 6x5 =30 or if you have to do 6x5/2! =15 ?

 

[idriss1]

I wasn't sure if you just do 6x5 =30 or if you have to do 6x5/2! =15 ?

That's what im confused about too. But im pretty sure you divide by 2

 

[paddydbarry]

Scan please guys?

You are correct, you must divide by 2 factorial, which is 2.

 

[georgiee_]

You are correct, you must divide by 2 factorial, which is 2.

Damn, I was tossing up and ended up going for just 6x5=30 instead.

Yeah, I think you're actually right. I got confused because I remember seeing a similar question which was "One is president and one is vice-president" but that's different because the order does matter.

It's alright, hey do you have a copy of the exam?

 

[gayforniall]
