    A warden of a prison is bored one day so he decides to play a game with the prisoners. He gathers all 100 prisoners in the cafeteria and explains the game. "You will all be lined up facing forward and a white or black hat will be placed on your head. Starting from the back of the line you must guess what color hat you have on. You can not touch the hate. You can look at all the prisoners in front of you, but not behind you. You can not touch any other prisoner. You can only say 1 word. If you do not guess the color of your hat correctly or break any other rules you will be shot in the head. You have 1 hour to think of a strategy to maximize how many will survive." With the best strategy how many prisoners are guaranteed to survive? What is the strategy?

    make a circular line!

    First off no, second off that doesn't even really help since you still can't see your own hat and can't say more than 1 word without getting shot

    1 prison guard: rush the guard and shoot them in the head.

    LOL Good luck with that, but there's a much safer solution

    The strategy is to simply tell the man in front what colour his hat is. That way, 99 are guaranteed to survive, assuming there is nobody in the line with the I.Q. of a glass of water and he forgets the strategy. The first man has a 50:50 chance of surviving.
    That's my thinking. It's wrong isn't it?
     
  9. JJJIrish05

    JJJIrish05 Sergeant

    Well 99 is correct with how many you can guarantee survive but I think your strategy is wrong. Because you can only say 1 word, so if the guy behind you says white (which means yours is white) then if you say white you live but if the guy in front of you has a black hat then he dies if he says white too.

    In that case, can they agree on four words that are coded to mean 'I have a white hat, yours is black/white', but that word starts with the word black (to denote their own hat colour, followed by a word that can be preceded by the word black or white.)
    That is, maybe the first guy guesses his hat is black and the agreed code word for 'my hat is black, yours is black' is blackboard (black is the colour of his hat and board is the code for your hat is black.) Therefore, he has described the colour of his hat and passed on the colour of the man's hat in front of him while using only one word. For example, my hat is white, yours is white could be whitewash. Black/white could be blackwater and white/black whitebait.
    Do I win a prize?
     
  11. JJJIrish05

    JJJIrish05 Sergeant

    No... I guess a better way to phrase the rules would be to say you can only say the word 'white' or the word 'black'
     
  12. joey off the street

    joey off the street Lounge Lizard No.1

    Handclaps! One for black, two for white. Or visa versa.
     
  13. JJJIrish05

    JJJIrish05 Sergeant

    Nope... The answer does involve only saying white or black
     
  14. JJJIrish05

    JJJIrish05 Sergeant

    anyone still trying to figure it out? or should I just post the answer?
     
  15. red death68

    red death68 Command Sergeant Major

    well iv got to admit im stumped but i dont want the answer right away maybe just a hint would help the process
     
  16. JJJIrish05

    JJJIrish05 Sergeant

    counting is key
     
  17. red death68

    red death68 Command Sergeant Major

    hmm thats a good one maybe they use one and two as a code to tell who has what since they were told they could only say one word nothing about numbers?

    i dont think its right though

    Could you please PM me the answer:)

    I would use the tone of the word to indicate to the next person what color of hat he wore.

    You are wearing a black hat: I will say the color of my hat in a low tone.
    You are wearing a white hat: I will say the color of my hat in a high tone.

    This way, all prisoners except the first one will survive. The first prisoner has a 50/50 chance.
     
  20. JJJIrish05

    JJJIrish05 Sergeant

    one is a word :p

    the answer does involve ONLY saying white or black, no hand signals, no sneezes, no coughs, no mirrors, no crazy dance moves, just black and white

    it's simple but surprisingly genius

    Riddle: There was a princess that two men were madly in love with. The King pointed at a tower and told them, "the person who's horse is the last to arrive at that tower will marry my daughter." They both then dash to the stables, mount a horse, and start racing towards the tower. What is the logic in this?
     
  22. Senlis

    Senlis Staff Sergeant

    What about my answer?
     
  23. JJJIrish05

    JJJIrish05 Sergeant

    Well it's not the answer I was told so there might have been something about tone in the rules that I forgot
     
  24. Senlis

    Senlis Staff Sergeant

    By any chance is there 50 black hats and 50 white hats?
     
  25. JJJIrish05

    JJJIrish05 Sergeant

    No, could be any number or each
     
  26. red death68

    they are riding each others horses

    99 of them survive ! How ? They all form a circle facing each other and the first prisoner tells the second the colour of his hat and the third and so on till he has told all the others, then there one word will be the colour of their hat and the first man who walked round telling all the others gives his life to save the other 99 ! Am i right ?

    Or my other solution to this is they are in a cafeteria so they all go for a cup of coffee and half of them get a black coffee and the other half white coffee and sit opposite each other one with white coffee one with black coffee they point to the coffee to indicate whether the other prisoners hat is black or white and after pointing then that man can say the colour of his hat and that is the only one word he says and he is not looking at the man behind him he is looking at the man sat opposite him and after the first two men have spoken the next two do the same thing and so on until they all have done it and they all survive ! Am i right ?
     
  28. JJJIrish05

    JJJIrish05 Sergeant

    No, if he says more than 1 word he gets shot instantly

    No, I said there is no lame tricks, the answer involves only saying the word white or black, it's simple but clever
     
  29. red death68

    red death68 Command Sergeant Major

    this sounds like a lame trick but is there a mirror involved? (i doubt it)
     
  30. rustyjack

    rustyjack MajorGeek

    He's already said no mirrors earlier on in this thread !
     
  31. Senlis

    Senlis Staff Sergeant

    I think I have an answer, but it requires that, with the prisoners facing forward, the person in the front starting and they go to the rear.
     
  32. red death68

    red death68 Command Sergeant Major

    lol i over looked that hmm imk stumped maybe itll come to me later got to admit this beats any of my riddles....

    Just as a matter of interest, i'd just like to point out that we would all be dead now as its took us lot a hell of a lot longer than an hour to work out ! :-D:-D:-D

    The last person in line counts the number of white hats ahead of him. If there is an even number, he says black. If there is an odd number, he says white. There is a 50/50 chance he will be right.

    The next person in line knows how many white hats the person behind him saw. If previous guy said white (odd), and he sees an even number of hats in front of him, he knows his hat is white. He can use this knowledge to deduce if he is black or white.

    This will continue on for every person up the line.
     
  35. JJJIrish05

    JJJIrish05 Sergeant

    You wouldn't all be dead, you still have a 50/50 chance of guessing right :-D :p
     
  36. LI_Geek_95

    LI_Geek_95 Post-and-Run Geek

    But theres not 50 white and 50 black
     
  37. Senlis

    Senlis Staff Sergeant

    It doesn't matter. If the person in the back sees 74 white hats, he guesses black. It doesn't matter if he dies.

    The next person knows the person behind him saw an even number of white hats. If that person now sees an odd number (73) than he knows his hat is white. If he still sees an even number of white hats (74) than he knows his hat is black.

    key: even = black; odd = white.
    edit. There are cases you have to consider what the last 2 or 3 people said. If one person sees 73 white hats and guesses white, the next person knows he saw odd number of white hats. If he now sees 72 white hats, than he guesses white also, even though it is an even number of white hats. The next person in line has to take this into consideration.
     
  38. JJJIrish05

    JJJIrish05 Sergeant

    CORRECT!!!!! (you can switch which colors are counted and said by the first person obviously)
     
  39. LI_Geek_95

    LI_Geek_95 Post-and-Run Geek

    Wow, we would be dead right now!
