4 criminals are caught and are to be punished. The Judge allows them to be freed if they can solve a puzzle. If they do not, they will be hung. They agreed.
The 4 criminals are lined up on some steps (shown in picture). They are all facing in the same direction. A wall seperates the fourth man from the other three.
So to summarise:-
Man 1 can see men 2 and 3.
Man 2 can see man 3.
Man 3 can see none of the others.
Man 4 can see none of the others.
The criminals are wearing hats. They are told that there are two white hats and two black hats. The men initally don't know what colour hat they are wearing. They are told to shout out the colour of the hat that they are wearing as soon as they know for certain what colour it is.
They are not allowed to turn round or move.
They are not allowed to talk to each other.
They are not allowed to take their hats off.
Who is the first person to shout out and why?

I guess Man1. He can see Man2 and Man3 with a black and white hat each. He assumed there would be some sequence. Black first, white next and so in all probability his would be black and assuming that he shouts 'Black'. I know it's only a possibility. But among the four he has a better chance of guessing than any one else because he sees 2 of them while Man2 can see only one and the other two none.
