Management. Six candidates for manager of a department store are ranked according to the weighted average of several criteria. How many different rankings are possible for the top four candidates if no two candidates receive the same rank?
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?
nope thats what the question reads
A) 1296 B) 30 C) 24 D) 360 E) 36
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
you think it can be a combination C(6,4)?
that gives the number of groups of 4 you could pick.
I dont think that's what it is asking
answer is not even on their if it was
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
you get to pick what you think it means i geuss
yea... ima go with 24
