шестое чувство

[barzel]

В эксперименте участвовало 30 слепых. Каждого слепого привели в закрытую комнату и поставили его напротив 5 цветных ящиков(цвета разные). Каждому слепому были выданы 5 записок в соответствии с цветом ящика, и попросили каждого из них подобрать правильный ящик к записке.
Перед вами результаты эксперимента:
Каждый из них сумел подобрать по крайней мере одну записку.
10 смогли ровно одну
6 смогли ровно две
4 смогли ровно 3

Вопрос: сколько людей смогло подобрать ровно 4? и сколько ровно 5?

be sure, this problem has solution. it has sufficient facts to solve it.

Ok, several questions, if I may:

1. Is the solution based on the theory of probability?

2. Were these experiments done in some sequence, e.g. the first blind person was in the room, then the second, then the third or each blind person was in his/her own room? Do the results of the previous blind person affect the next in a row? Do these blind people communicate between themselves?

3. Do all these blind people receive their paper slips in the same sequence, e.g., for instance:

1- red
2 - blue
2 - black
4 - white
5 - pink

4. Do the experimentators use the same paper slips for each experiment?

Thanks in advance.

why do you not authorithed?

answers:

1. not exactly, the promlem is based on pure logic, nothing probability

2. whole experiment occurs simultenusly

3. if it'll help you can propose it

4. it's doesn't matter

Ok, my former work colleague explained it to me. How stupid I now feel

I didn't authorize because I don't have an account. I'm reading my husband's journal His nick is d******t.

So do you know the solution now?
say, it was very simple, therefore i choiced it to post here. usually people tend to think in hard way, often solution lay on surface

Exactly. I often can not solve the obvious puzzles, but can crack the more complicated ones. But I can not solve really complex. Do you know more puzzles? I like them. I also know quite a lot.

don't over think it, the answer is very simple, it's pure Logic.
