No.

1) 16
2) (0.5^10)x2
3) 175cm3

1. Wrong, I think. 9 red, 7 green.
2. Should be something like total combination plus 1. I don't know, the question is weird.

>>8605308

Not even a thank you or response. Asshole. Leech.

1. 9+8+1
2. 2^10 + 1
3. (1/2) * 10 * 5 * 7

not op

can someone explain how to figure out the second question?

>There are 10 questions on a test paper. They can be answered with either yes or no. How many test papers are needed so that at least 2 of them have the same combination of answers?

Two.

I think the way you are interpreting the question the answer is three. All yes and all no are two possible sets that haven't got the same answers.

>>8605308
1. In the worst case scenario you first pick the 9+8=17 balls. To ensure that you get all 3 colours you thus need 18
2. For every question there are two answers, so for 10 questions there are 2^10 combinations possible. If you have (2^10)+1=1025 tests, at least two of them will have the same answers.
3. 0.5*10*5*7=175 cm^3

No, I think the question is asking about the worst case scenario. Even though it is pretty ill defined and I'm guessing.

let's say I have 2 questions instead of 10, all possible test papers are:

>1. Yes Yes
>2. Yes No
>3. No Yes
>4. No No

If you have 4 papers, you are not assured to have two identical ones, because they could be all different. But if you have 5, assuming all questions have been answered, it will have a repeated paper no matter what.

I didn't know that triangle's area was invariant if given one side and it's height
but if it's right, total awnser should be (9+8+1)+(1024+1)+((5*7*10)/2) = 1218, unless there is some trick with the unit of the volume

Good job /sci/, work out everything for OP, so he's kept being stupid.

Wow, my synesthesia is really fucking with me as I read the first answer. Nine is actually dark grey, eight is cerulean, and seven is yellow. None of this makes sense. Is it okay if I change the colours, or will you call the internet police?
