In a game show, The Three Stooges; Moe, Larry and Curly entered the room, each with a hat on their head. There were two colors of hats: Black and Red, which were assigned to them randomly. Each person could see the hats of the two other people, but they couldn't see their own hats. Each person could either try to guess the color of their own hat or pass. All three do it simultaneously, so there was no way to base their guesses on the guesses of others. If nobody guesses incorrectly and at least one person guesses correctly, they all share a big prize. Otherwise they all lose.
Before the contest, The Three Stooges had a meeting during which they decided their strategy. What might be the best strategy?

Dead or Alive battle is going on between "Daya" and "Abhijeet". The referee "ACP Pradyuman" has two papers with him -- one with "DEAD" written on it and other with "ALIVE" written on it -- Both papers are folded up and placed in a bowl. Daya is permitted to pick out one of the papers (without looking), and if he choose the one with "ALIVE" written on it, he will come out alive by winning the battle. Otherwise, he will die.
On this occasion, a mean-spirited acquaintance of Daya, bent on his demise, has substituted the paper with "ALIVE" written on it with another one with "DEAD" written on it. This person gleefully informs Daya that he is doomed to die. Daya is not permitted to speak to anyone about this misdeed, nor he has a chance to switch the papers or the bowl. How can Daya win the battle?
