You and nine others have been captured by super-intelligent alien overlords. Aliens think humans look delicious, but their civilization prohibits eating highly logical and cooperative creatures. Unfortunately, they’re not sure if you qualify, so they decided to test you all. Can you solve this hat riddle? We have solved it here, let’s take a look!
-
Let’s see what happens if the hats are distributed this way. The tallest hostage looked ahead and saw three black hats; he said “black,” telling the others that he saw an odd number of black hats. He misjudged the color of the hat, but that’s okay because everyone can make a mistake.
-
Prisoner #2 also notices the unusual proportions of the black hat, so she recognizes that her hat is a white hat and reacts correctly. This suggests that this must be one of the black hats spotted by the first two prisoners, with prisoner number three noticing an even number of black hats.
-
Upon hearing this, Prisoner No. 4 understood that since one black hat was missing, she should go back and look for the same number of black hats.
-
However, she only noticed one, leading her to believe that her hat was also black. Between five and nine prisoners were each looking for an odd number of black hats, which they found, leading them to deduce that their hats were white.
-
Now it all depends on you at the front of the line. The unusually high number of black hats noticed by the ninth prisoner could only mean one thing.
-
You’ll see that this strategy works for any feasible hat configuration.
-
The probability of the first prisoner misidentifying his hat is 50%, but because he provides the odd-even information, the others can identify their hats 100% accurately.
-
Everyone initially expects to encounter something unusual or an even number of specified color caps. If the numbers they calculate don’t match, they must have a hat of that specific color.
-
Each time they do this, the person behind them in line changes the parity they expect to see. That’s all; you can leave now. These aliens seem to have to starve or find other, less sensitive creatures to abduct.
