Labyrinth Discrete Math

[McGivski]

I'm probly wrong, but I think the red one is telling the truth because it says the only way out is through these doors, which it is the only way out

[UNR3S7]

Since blue told her the rules, and one of them always lies, wouldn't he have to be the truth teller if the game was true, since otherwise, he would have lied about the game and the entire situation would be invalid?

Or is the truth/lie only applied to questions that are true/false?

[Breathlessdratini]

I might of thought of a way to find out who's lying and who's telling the truth with 2 questions. I would ask the red one if the he was wearing any red. Then I would ask if the door behind him leads to certain doom.

[RyokaiTheGreat]

@Breathlessdratini Anybody could easily figure this out with two questions -_-

That's why they said that she could only do it with one question..

[chica476]

Truth tables help a lot in problems like these.

[agrainger58]

Ok, I think I finally have this worked out in my head. She basically asked a question that unified the responses.

Would Blue say to take the left door?

If Red is the Truth Teller, he must say that Blue will lie. (Because that is the truth)

If Red is the Liar, he must also say that Blue will lie. (Because that is a lie)

Therefore, whatever response you get will be the lie. So do the opposite and take the other door (the correct door).

P.S. You never actually know who is the liar.

[Mightymilky]

@agrainger58 you can know who is the liar by asking one of them: "What would the other person tell about you? (liar or not)" Liar would say "not liar" while Not liar would say "liar".

[RyokaiTheGreat]

@Mightymilky This doesnt work at all. Since you don't know which is which yet, YOU CAN'T TELL WHO'S LYING!

[CeroMetralleta]

@fuze44 SEXIST !

[DontrelleRoosevelt]

I don't get it! Makes my head hurt.

[jfeltz]

God of War 1, Pandora's Temple Levels. Not necessarily this exact puzzle, but the set design/theme.

[MIT2004]

@jfeltz what part?

[atarom]

LONG LIVE SMULLYAN

[chocobosROK]

she pwned them.

[sakerlygood]

I've seen this before. This is a movie right? Can anyone tell me which movie it is?

[MrEinsteinz]

It's called Labyrinth. Lol. It was made in 1986.

[gpardhu]

this chick is too hot..ive to close my eyes and understand wat she is sayin..she is great fuck buddy

[fuze44]

No woman is that logical.

[KensaimasterWung]

Yeah. Their brain is not equipped to deal with such real world concepts.

[conairspy77]

@KensaimasterWung i kinda envy them, for my major i pretty much live in my own world...so i do feel jealous that there are people who live in a more natural setup than me...lol

i would say, lucky for girls

[IronJackalTw]

fuze44,

YOU stay in the BARS with drunks like Lindsay Lohan for far too long! >=P

Ever heard of "Hypatia of Alexandria"!?

[pickitupp]

Yeah, we did a few puzzles like this in our discrete math class, having something to do with an Island of Knights and Knaves.

[LiquidCreek]

and just think, this is usually the first chapter (Logic) of a high level 200's math course.

[hanumizzle]

The material that comes later (e.g., probability, graphs, groups) is easier IMO.

I hate these Knights and Knaves problems! ^^
