Riddle...
Four prisoners are lined up on some steps. They are all facing in the same direction. A wall separates the fourth man from the other three.
So to summarise :-
Prisoner 1 can see prisoner 2 and 3.
Prisoner 2 can see prisoner 3.
Prisoner 3 can see none of the others.
Prisoner 4 can see none of the others.
The prisoners are wearing hats. They are told that there are two white hats and two black hats. The men do not know what color hat they are wearing. They are told if they can shout out the correct color of the hat that they are wearing, they will all be granted freedom. But if they shout out the wrong color, they will all be executed.
They are not allowed to turn round.
They are not allowed to talk to each other.
So the question is -
Who is the person to shout out?
How does this prisoner know for sure?
