You are traveling alone in the woods, and are lost. On the verge on dehydration, you come across 2 doors. Standing in the way of the 2 doors are 3 trolls. There is a sign hanging above them:
“Behind one of these doors, is death. Behind the other, is freedom. You MUST choose a door. Guarding the doors are 3 trolls. One troll will always lie. Another will always tell the truth. The remaining troll alternates between telling the truth and lying (If the last question he got asked resulted in him lying, then the next question will result in him telling the truth). You may ask 1 question. You can ask it one troll, 2 trolls or all 3 trolls. Then, you may choose your door. Think carefully.”
What question can you ask and to how many trolls do you ask it to, that will result in your freedom?
Or is it impossible to extract the information you need with this scenario?
lunapark, you ask all three trolls. The truth telling troll says Door A (correct), the lying troll says Door B (not correct) and the third troll could say either A or B, depending on his whim at the time… So? How does this tell you which door to use.
Manta, how about you confine this to one topic rather than branching out?
