Tomcat Posted July 25, 2015 Share Posted July 25, 2015 The famous four hat puzzle which i think was originally about four French Legionaries Four Guys They can’t move – they can only look forward. Between A and B is a brick wall which is completely opaque (they absolutely can’t see through it). They are all aware that each of them is wearing a hat, and that two of them are wearing a black hat, and two of them are wearing a white hat. They don’t know what color THEYare wearing. However, each of them DOES know where the other three are buried. In order to avoid being executed, one of them must call out to the executioner the color of their hat. If they get it wrong, everyone will be shot. They can’t talk to each other and have only 10 minutes to figure it out. After 60 seconds, one of them calls out. QUESTION: Which one of them calls out? How can he be certain he knows the color of his hat? This is not a silly trick question. There’s no outside influence and no other way of communicating. They can’t move and are buried in a straight line; A and B can only see their respective sides of the wall, Ccan see B, and D can see B and C. 1 Quote Link to comment

seanbeag7 Posted July 25, 2015 Share Posted July 25, 2015 well if i was D i would wisper to C his hat was black, now C can see that B is wearing White, so D now has a 50/50 chance of fucking up, and if he is irish well i thisk he has better chance of not been shot...... Quote Link to comment
dixon cox Posted July 26, 2015 Share Posted July 26, 2015 QUESTION: Which one of them calls out? How can he be certain he knows the color of his hat? Answer = C If C was wearing white then D would have said black, but he said nothing. D's choice was the same as A & B's (50/50), so his silence revealed the answer to C.

Pdoggg Posted July 26, 2015 Share Posted July 26, 2015 I agree 100% with DC's conclusion and lucid explanation. Quote Link to comment
Tomcat Posted July 26, 2015 Share Posted July 26, 2015 yes , thats about it for the Hats .. well done DC Quote Link to comment

I still can't get it. Will sleep on it for another week. In the meantime, here's an easy one: A man and his son are in a car crash. The father is killed and the child is taken to hospital gravely injured. When he gets there, the surgeon says, 'I can't operate on this boy - for he is my son!!!' How can this possibly be? Hint: This has nothing to do with adoption or time travel. Quote Link to comment

Tomcat Posted August 5, 2015 Share Posted August 5, 2015 the triangle is a real impuzzibility... I dont know the answer either.. i have not looked.. Quote Link to comment
Tomcat Posted August 5, 2015 Share Posted August 5, 2015 Also PD the Two envelope question can be resolved as the QTY in the envelopes must be add up to a finite amount .. so the equation is meaningless unless the QTY allowed in the envelopes is infinity if the total amount adds up to 900 dollars then you pick the 600 one , its impossible to get 1200.. ( double).. thats the answer and i suppose it must be correct .... i must try that out in the bar next time as i think no one will ever get it even when you know the answer the question still seems to defy logic Its a real headache that one . 1 Quote Link to comment

Pdoggg Posted December 22, 2015 Share Posted December 22, 2015 This one is not easy: You work for a tech firm developing the newest smartphone that supposedly can survive falls from great heights. Your firm wants to advertise the maximum height from which the phone can be dropped without breaking. You are given two of the smartphones and access to a 100-story tower from which you can drop either phone from whatever story you want. If it doesn’t break when it falls, you can retrieve it and use it for future drops. But if it breaks, you don’t get a replacement phone. Using the two phones, what is the minimum number of drops you need to ensure that you can determine exactly the highest story from which a dropped phone does not break? (Assume you know that it breaks when dropped from the very top.) Quote Link to comment
Tomcat Posted December 23, 2015 Share Posted December 23, 2015 a toughy So far i think you may drop one phone from around floor 50 so then you got half left depend whether it breaks or not. How you get to a minimum after this i cant get it..... maybe tomorrow ill have another go.. the minimum must be below 50 im thinking Quote Link to comment
Pdoggg Posted February 19, 2016 Share Posted February 19, 2016 There’s an airplane with 100 seats, and there are 100 ticketed passengers each with an assigned seat. They line up to board in some random order. However, the first person to board is the worst person alive, and just sits in a random seat, without even looking at his boarding pass. Each subsequent passenger sits in his or her own assigned seat if it’s empty, but sits in a random open seat if the assigned seat is occupied. What is the probability that you, the hundredth passenger to board, finds your seat unoccupied? Quote Link to comment

If u drop it from 50 and it breaks then you next drop it from 1, then 2, then 3, and in the worst case case scenario it would take 49 drops. But is dropping from 50 the best course of action?

Torurot Posted February 19, 2016 Share Posted February 19, 2016 I got the cabin crew who finally got the captain who gave the arsehole an ultimatum to move to the correct seat or be removed from the plane. Quote Link to comment

stoolpusher Posted February 19, 2016 Share Posted February 19, 2016 Well having a bad flight this trip to Thailand ,I would probably end up sitting next to the worst person and have to put up with his or her shit the hole trip and probably lose my arm rest to boot. .... But I don't think that is the right answer. Quote Link to comment
