Number 1 sees number 2 and 3’s hats.

Number 2 sees number 3’s hat.

Number 3 sees only the wall.

Number 4 sees only the wall.

There are no mirrors.

They all know that there are 2 black hats and 2 white hats and that there are four people.

They know their placement in this room is as shown in the pic attached.

Can the four prisoners be freed? If so, how?

Answer:Prisoner (2) is the correct person for freedom.

If prisoner(2)’s hat just isn’t reverse prisoner(three). Then prisoner(1) gave the proper reply.

Bcoz if prisoner (2)’s and prisoner(three)’s hat is the identical colour then prisoner(1)’s hat will reverse colour…

Bcoz hats count is 2white and 2black.

So jail(2)’s hat and prisoner(3)’s hat is not going to the identical colour.

Then prisoners(2) never recognize the hat colour then so he’s going to.

Then prisoner(2) will just comprehend that his hat is the opposite color of prisoner(3)’s hat.

Then jail(2) gave always correct answered
