It's not completely clear to me what you're asking. So they are ranked 1 through 6 I'm geussing. Are you saying that the top 4 are selected, and then we want to find how many different ways we can rank those preselected top 4?

well if you want the different arrangements of the top 4 and they are preselected, you would have the permutations on 4 objects which is 4!=4*3*2*1=24

what throws me off is the 6

yeah it's strangely worded

If they mean there are 6 rankings and you pick 4 people and want to know the possibilities of ranking for them it is 6*5*4*3=360. I geuss you have to interpret the question
anonymous
  • anonymous
you think it can be a combination C(6,4)?
anonymous
  • anonymous
that gives the number of groups of 4 you could pick.

I dont think that's what it is asking

I would geuss they wanted the 6*5*4*3, but they said how many possibilities for the top 4, which to me means youre only permuting 1st 2nd 3rd 4th place which is 24
anonymous
  • anonymous
you get to pick what you think it means i geuss
