Brain Teaser, 4 hats and a wall

Recommended Posts

B W B [] W

Everyone is looking to the right and cannot see the color of their own hat or the one behind them. [] is a wall, so no one can see that the last person has a white hat and that last person cannot see the other three. Nobody can speak except to say "I have a X colored hat."

Who will speak, what will he say?

The second person will say "I am wearing a white hat."

The second person will know that their hat color is different from the person next to the wall, because if the second person and the person next to the wall were wearing the same color hat, then the first person would have known his hat was the other color.

Is there some sort of constraint that was left out here? Like, there are only two black hats and two white hats?



Yeah....I think you just busted bmcd308. Somehow he got the right answer without all the info. Think he say it before and was pretending he just figured it out :P

I posted this one before.

They know that there are two B and two W hats, just not which one they are wearing.

I just assumed they knew there were two white and two black. If there was not a finite universe of possiblities there, it would be impossible. Each would be faced with an infinite number of choices. "Uh, am I wearing a purple hat?"
