Its person 3 because he sees the other 2 with the masks on but the executioner has the other mask on so there is only one mask left so he knows the colour of it!!!!
This is a discussion on Riddle within the Entertainment board part of the General category; Person 3 is the answer. He sees on 2 of them, and he has the most chance of knowing that ...
I said the fourth mask is irrelevant, and the executioner does not wear, nor hold the fourth mask. Noone sees more than what I have said.
Okey, I have the answer... Without thinking about it, it got to my mind!.
Person 2 is the answer. 2P (Person) knows that the Executioner, won't give him a red mask, as 1P got a red mask. If the executioner did that, then 3P would know that he gets a blue one. That way 2P can know with 100% security that he gets a blue mask!
As Person 3 doesn't say anything, Person 2 knows that he has the opposite of Person 1, or else Person 3 would have known what color he had.
Got any more epic riddles like that one?
