There are 5 kids who just got 12 candies for halloween and they have to share it. Youngest one has to propose a way to distribute the candies among the kids. Then, they proceed to vote, and if the strict majority rejects the proposition, the youngest kid is evicted and leaves with nothing. And the 2nd younger kid will then have to propose a distribution, and they will again vote for it, and may or not accept or evict this kid. And this goes on, until the distribution is accepted. Assuming that there are all loving candies and are not friends (they don't matter if a kid is evicted), what is the distribution the youngest have to make in order to get some candies ? + Show Spoiler + 2 + 4 x 2.5 = 12 nop. Can't break the candy. When a kid proposes a sharing, the other ones when voting, will think "If I evict him, will I get more candies ?" And it is actually about optimal choices. + Show Spoiler + start with 2 kids. Youngest takes all the candies because the strict majority can't reject it. So its 12-0. If you have 3 kids, the 2nd youngest knows knows if he votes the youngest off he gets all the candy so he always votes the youngest off. The oldest knows if he votes the youngest off he gets none. So you give the oldest 1 candy. 11-0-1 If you have 4 kids, the 2nd youngest knows he can get 11 out of 12 candies if he votes the youngest off so hes always going to vote the youngest off unless he gives him 11 candies. Youngest can just give one candy to the 2nd oldest now because if it gets to the case with 3 kids he gets none. 11-0-1-0 So with 5 kids, 2nd youngest always will vote youngest off unless he gets 11, so youngest should give 1 candy to the oldest and 1 candy to the middle position because they get none if youngest get voted off. 10-0-1-0-1

It is incredibly important to be able to identify a problem that is impossible to solve with a direct mathematical approach, that has to be worked around. Many very intelligent people have wasted huge amount of time trying to solve impossible problems. In real life you will not know if the problem you have in front of you is solvable with mathematics, or if you need "creative bullshit".

that has to be the worst rationalization ive heard.

Many intelligent people would have saved so much time if they only knew smartass responses to ridiculous newspaper fun trivia questions.

I gave a perfect example why its ridiculous, ill give 99999999 : 1 odds question, see?
