13!/[(13-2)!2!]

i think that's right, but let me double check

18 DAYS

yep, 13C2

all possible ways to choose 2 team out of 13

how are you all getting those?

and i've tried 13C2 @pizzapi it's not that

12 days. <-'
I guess

no. it's supposed to be 13 gamedays with 6 games each. but i don't know how

13C1?

wait, so all the teams play 6 games each?

i have no idea. i suppose it means each day has 6 games

13C2 divided by 6

since 6 games per day

but how do you know 6 games per day?

it wasn't given

6 teams can play 1 game everyday

that's the maximum possible games

per day

it's looking for minimum though

no, its 13 days, with 6 games per day

because a maximum of 6 games can be played per day

12 teams can play 6 games on day 1
repeat for day 2
etc.

i still don't get the logic why that's the solution

total games=13C2

maximum games per day=6

minimum days=total games/max games per day

@ganeshie8 each team can only play 1 game for day

*per

if you divide total by max..won't that make the final answer max?

oops ! bad logic disregard that

no cuz the minimum would be 1 game per day

you are trying to minmize the number of days, by fitting the most games in one day

I don't think you're reading the whole question and given correctly.

what dp you mean @panlac01 ?

is there a different solution?

13C1 gives the same result though...

13 teams..one game per day...so 13C1 would make sense right?

no, there must be a total of 78 games

13 teams must play all the other teams

isn't that what 13C1 means?

with 13 teams, only 12 teams can play in one day

no 13 C 1 means the number of ways you can select 1 team from 13 teams

so what are you implying?

12 team playing on 1 day=6 games in total for the day

this was a question in a board exam back in '94 so it's meant to be tricky

in the first day, you are left with one team unable to play

so you need to move on to the second day to give that specific team who didn't play to play.

i really think 13C1 makes sense

in the case of (13C2)/6...why divide by 6? of all the numbers?

6 is the number of games played in 1 day by 12 teams

but what about for the case of 13 teams?

only 12 teams can play per day because they have to be grouped in teams of 2

i don't think that means the other team should be disregarded

its a 1v1 match, 2 teams per game

yes i get that. but im asking for the case of 13 teams. is that logic applicable in that case?

you used 13C2 and then divided by 6 (which is for 12 teams)

*groups of two teams out of 13 teams

so what is the answer with the formula being suggested?

ganesh is close

(13C2)/6
I really need to work on explaining things, hopefully openstudy will help me with that

don't worry bro, you got it from the first time. Illustration makes a better explanation sometimes.

so do you agree with pizzapi already @panlac01 ?
