EPTWich means its easier to get 2 different sides faced up than for example head head.

Consider the questions: Is the Car Behind door 1 or 2? and Is the Car Behind door 2 or 3? C = car, G = goat. Doors are presented in order from 1 to 3 Case: CGG Yes, No GCG Yes, Yes GGC No, Yes Now, for our questions to ask the watch, use the following: Is the answer to the question "Is the car behind door 1 or 2?" blue? Is the answer to the question "Is the car behind door 2 or 3?" blue? Blue = Yes, Yellow = No cgg Blue, Yellow gcg Blue, Blue ggc Yellow, Blue Blue = No, Yellow = Yes cgg Blue, Yellow gcg Yellow, Yellow ggc Yellow, Blue We get the same results irregardless of the truth values of the watch. If Blue, Yellow pick door 1, If the answers are the same pick door 2, If Yellow, Blue pick door 3. No. This still leaves you with a 50/50 cause you won't know if it's door one or three considering the fact that you don't know which light means no or yes. | ||

Mad props to those who got #2 - the hardest part about it is that the solution: + Show Spoiler + Would you flash yellow if i asked you if there was a car behind door 1? Would you flash yellow if i asked you if there was a car behind door 2? I picked this cause it was best phrasing isn't a EUREKA solution at all | ||

Rek, look at the cases. You don't need to know which means yes or no because the cases are the exact same for each situation. The only thing that is different is the blue, blue or yellow, yellow outcome, but we just check to see if the color is the same. The actual color doesn;t matter in that case. | ||

And blue = no, how can it respond with a blue light? It's contradictory, no? | ||

You just have to start from the inside and work your way out. Take the CGG case. Is the car behind door number 1 or 2? Yes. What is yes? Yellow. Is the answer blue? No. What is no? Blue. Done. Edit: To clarify, it isn't asking "Is the answer to this question blue?" It's asking "Is the answer to this other question blue?" | ||

You ask it "Is the answer blue?" It flashes a blue light. That's not a paradox to you? Telling you the answer is not a blue light by giving you a blue light? | ||

The brick going into the water does not displace any more water than it did when being supported by the canoe. This has been solved like 9 on pages 2-4. Your solution is wrong. I'm also discouraged by the people who can't do simple probabilities that you learn in grade 10. You flip two coins, here are the probable outcomes: (HH, HT, TH, TT). So for that guy who keeps saying that it's 25% same and 50% other (which doesn't even make sense in itself because that doesn't sume to 1), please stop. | ||

(heh not really but you didn't prove me wrong) If there is one goat in 1/2 and 2 in 2/3 then the answer to one is no and the answer to 2 is no. The no no situation I described. So there there must be 1/2 goat in one or 0 goats in 1/2. If there's 0 goats, then then there must be 2 in 2/3 which means there's 1 in 1/2 and thus impossible. If there's 1, it can be either 1 or 2. If it's 1, HERE'S WHERE I LOST YOU then there CAN ONLY BE 1 goat in 2/3. IF there is only one goat in 2/3 THEN THE ANSWER TO SECOND QUESTION MUST BE YES. So the whole thing is impossible. There is no NO NO (wrong wrong) | ||

i think your's is the nicest answer but wrong: car in door 1 Q1 Are there exactly 2 goats in 1/2 : NO Q2 Is there exactly 1 goat in 2/3 : NO say blue blue car in door 2 Q1 Are there exactly 2 goats in 1/2 : NO Q2 Is there exactly 1 goat in 2/3 : YES say blue yellow car in door 3 Q1 Are there exactly 2 goats in 1/2 : YES Q2 Is there exactly 1 goat in 2/3 : YES say blue blue so it can't tell the diffrence between 1 and 3 Even if i'm wrong you've only got 2 light combos which can at most identify 2 doors, what if it's behind the 3rd? | ||
