Answer 8

the table is given as hint

Answer 9

idk i guessed tbh

Answer 10

What happened to snooker?

Answer 11

college didn't have enough money

Answer 12

snooker = 0 ( no participants)

Answer 13

why is badminton \(n-1\), is that the rule?

Answer 14

I actually looked up this question in there is a text that says the answer is C. I don't get how they got it...
There are 6 students we are still trying to place.
So
T,B,TT
6,5,... too many already throw this combination out
5,4,1 seems possible since J is a TT but we know there could be more because of the choices...
4,3,3 so 3 could play TT
2,1,7 ...
1,0,9 ...
the last 2 don't make sense

It seems it would be a chose with 3 people not 4 so I don't know how they got C

Answer 15

@ uncle due to this statement ->The badminton team has one student less than tennis team.

Answer 16

a choice with 3 people not 4*

Answer 17

i guess it say COULD... like there might be 3 people who actually play TT but we aren't given enough information to actually know the 3 people

Answer 18

like and some how are we can narrow it down to 4

Answer 19

it is like this text assumes a non tennis play is also a non-table tennis player

Answer 20

this question too confusing

Answer 21

yes ^ it is but i thought the table might somehow help to solve it

Answer 22

I'm not sure if this helps, but you can see that but an odd number of of students must play Table Tennis

Answer 23

I don't get the part "or as a group"

Answer 24

means A,B and C cannot be all in single team like tennis or badminton or table tennis

Answer 25

We have a total of 10 people.
So far, we only know 1 person is in TT. That is J.

We have 9 people left.

Our answer choices gives either a total of 4 players or a total of 3 players.
If we have a total of 4 players, then we will have 3 badminton and 3 tennis players. We cannot take 6 people and split them into the two teams so that one team has 1 person more than the other.

If we have a total of 3 TT players, we can have a total of 7 tennis and badminton players. Do you see where I'm going with this? That means, we can then have 4 tennis players and 3 badminton players.

Now, there are only 2 answer choices that have 3 players for TT. That is answer choice A and answer choice B. If you look at answer choice A, you can see that they say that G will be playing TT. But, we know from the question that G doesn't play.

That leaves us with B as our answer.

When I looked at this question, my mind was going all over. But the minute I started writing it down, it all become clear to me :)

I hope this helps! If you have any questions, feel free to ask. :)
