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.

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.
