if the green box is true it's the middle one
if the polka is true then you get a contradiction because the middle box being false means that the gift is both in polka and middle
if the middle one is true then you get a contradiction because polka being false means it isn't in polka, and the green box being false means it is in polka

so it's the middle one.

>> No.10202073

The middle, right?
If the left statement is the true one, than the middle one is false, so the true middle statement would be "the gift is here", which contradicts with left statement.
If middle statement is true than left statement is actually "the gift isn't in polka dot" and right statement is "the gift IS in polka dot", again a contradiction.
If right is true than the gift isn't in the polka dot one, IS in the pink one and is not in the polka dot one, and here we have no contradiction.
so middle.

If it's in the Polka dot box, then two of the statements are true: "It's in here" and "The gift is not in here". Since only one statement is true, it cannot be in the polka dot box.

If it's in the green striped box, then again, two statements are true: "The gift is not in here" and "The gift is not in the polka-dot box".

By elimination, it's in the middle box, and the one true statement is "The gift is not int the polka-dot box".

First pretend the gift is in the Left one.
Check how many labels are true if it is there.
2/3 labels are true, but only 1 is supposed to be true.
Therefore it is not in the Left one.

Next pretend it is in the Right one.
Check how many labels are true if it is there.
2/3 labels are true, but only 1 is supposed to be true.
Therefore it is not in the Left one.

Lastly pretend it is in the Middle one.
Check how many labels are true if it is there.

Therefore it is in the Middle one.

No, the question STATES that two of the boxes are lying to you while one is telling the truth and then ASKS you to figure out which one actually has a present in it. The one that has the present in it doesn't have to the one that is telling the truth. In this case the one on the right is telling the truth but the middle one is the one that has the present in it.

Once you understand that the solution is pretty trivial.

Make sense?

Without looking at the thread, i'd say that the striped box on the right is correctly labeled and that the gift is in the pink box.

Reasoning: If the dot box's label is correct, then so will be the label on the pink box but only one label can be the correct one. The striped box says nothing about its own contents but the pink and dot box do and if the striped box is correct, then both other boxes are lying and thus, the pink box contains the gift while the striped box is correctly labeled.

If the label on box 2 is true (meaning that the other labels are false) then the present is in box 3. Similarly if we take the label on box 3 to be true then the present is in box 2. This cannot be solved without opening the box and finding out.

If the pink box's label is correct then you will get a contradiction. Dot box says it contains the gift while the striped box says that the dot box is lying and doesnt have the gift. Both of them cant lie at the same time.

probably
i mean,
if you *don't* have mercury poisoning—which, if you have ever had "silver" amalgam dental fillings, you almost certainly do to some degree, and it will forever hinder your body's ability to function properly until it is removed—emeramide is still a very potent antioxidant with a long half-life, is lipid-soluble, and is without apparent toxicity (with oral doses in rats in excess of 0.5% their body weight not causing any apparent problems)
if you *don't* have apparent cognitive problems, many nootropics still are neuroprotective (and even neurogenerative, in the case of things like noopept, semax, P-21, lion's mane—many of which (all of which?) are peptides, but the list goes on) in addition to being able to increase athletic performance and (in many apparently healthy people) stimulate the process of learning
if you *don't* appear to have other organ problems, i can say in all earnestness that NUMEROUS biologically active peptides still appear to be extremely beneficial (extending telomeres and repairing damaged DNA, which almost certainly optimizes organ function even in healthy individuals (and has restored organ function in the sick)), and oftentimes extremely low-risk
i'm gonna be trying to get some bronchogen, honluten, vladonix, and taxorest for my lungs soon—but, there are other short peptide complexes, of course, that work to restore optimal cognitive function in particular
pinealon comes to mind

absolute coolest area of medicine; if you look into these short peptides, you'll see a good number of anecdotes that mention very positive results with their use

Look at it like a Boolean system. Present in box can be 0 (false) or 1 (true).
Statement can be 0 (false) or 1 (true).

There is only one possibility. The middle box has the present and the right box has the true statement.

you're not compsci, you're a pajeet, use simple predicate logic (a,b,c are Statements "Gift ist in Box"):
statement A:=a
statement B:=-b
Statement C:=-a
combine these into one:
P=a^-b^-a
eliminate a and -a because of contradiction
this leaves us with
P=-b but because P has to have a box b ist false making it contain the gift.

suppose label 1 is true. this would imply 2 others false and a gift present in 1st box. but then statement 2 is false which would imply gift in box no 2, but there is only one gift- a contradiction.
suppose statement 2 is true. then 1 and 3 are false, so gift is not in 1 and not in 2 by assumption. staement 3 being false implies gift being in box no 1, but as we have shown assumption of statement no 2 being true implies thats not possible- a contradiction.
suppose, at last, that statement 3 is true. then 1 and 2 are false. it impies gift being in box no 2 and no contradiction is impied and since one of the boxes contains a present, it must be the box no 2.

1) Assume a straightforward, non-trick-question prompt: "gift" and "present" mean the same thing, "gift" isn't to be interpreted in its German language sense as "poison", The prompt itself, with its conditions, is not to be taken as one of the "labels", of which there are three.

2) Consider that the three possible locations of the present are a distinct matter from the three given statements, which also refer to the boxes and the present, but need not be coupled directly with them as in the graphic (a sly ruse to trip up the double-digit IQ bunch). There are two triplets of propositions, and exactly one of each triplet must be true. Moreover, (a subtlety), exactly one of the nine ordered pairs of the two triplets' Cartesian products, with their immediately entailed consequences per the prompt (the other four props are false), must be true (it is possible to imagine analogous situations in which multiple distinct such ordered pairs in a given analogous problem are true, a very very dumb-simple exercise left to the reader (hint: identity) defeating the spirit of the given problem).

3) For convenience, label the boxes themselves "a-c", from left to right. Let A-C be the propositions "The present is in box a-c" respectively. Let [math]\alpha, \beta, \gamma[/math] denote the three given statements, also propositions. The problem is to inspect the nine elements of the Cartesian product A, B, C x [math]\alpha, \beta, \gamma[/math], finding exactly one ordered pair having both components true, and with the other four components not written immediately given as false per the prompt. If such exists, the problem is consistent. If not, not.

4) Observe/derive about 10 or so useful manipulation rules.

5) Inspection. Given that there are only nine cases, we propose inelegant brute force. 8 immediately entail not-"greek", but imply "greek" per the inference rules. Only (B, gamma) is consistent with all of the derivable rules, so the problem as given is consistent.

Cont, some detail on the inspection in this treatment.

Five rules (given in one version, here) constitute the complete structure of the problem, and the necessary logical relationships of the six propositions as given in the problem's statement, together with the "exactly one-of-three" language about each triplet. These rules can be supplemented by their valid transformations, other general rules of inference, etc. In order for a case to be valid, these five rules are (one statement of) precisely the system which must not be violated on any point.

1) [math]A \iff \alpha \iff ¬\gamma [/math]
2) [math]B \iff ¬\beta[/math]
3) [math]C \implies ¬\alpha [/math]
4) [math]C \implies \beta[/math]
5) [math]C \implies \gamma[/math]

Nine ordered pairs of statements must be checked. For example, the pair [math](A,\alpha)[/math] entails that both of its components are true, and that all four other components not given are false. So, in this case we have [math]¬\beta[/math]. But by negation of 2) the pair also implies [math]\beta[/math] itself, a contradiction. This approach can be used to rule out 8 of 9 cases. One possible approach is finished below:

[math](A, \beta): ¬\alpha, \implies \alpha \; (1)[/math]
[math](A, \gamma): ¬\beta, \implies \beta \; (2), negation) [/math]
[math](B, \alpha): ¬\gamma, \implies \gamma \; (1), negation)[/math]
[math](B, \beta): ¬\gamma, \implies \gamma \; (1), negation)[/math]
[math](C, \alpha): ¬\gamma, \implies \gamma \; (1), negation)[/math]
[math](C, \beta): ¬\gamma, \implies \gamma \; (1), negation)[/math]
[math](C, \gamma): ¬\beta, \implies \beta \; (2), negation)[/math]

This leaves [math](B,\gamma)[/math] which entails/fixes [math]¬A, ¬C, ¬\alpha, ¬\beta[/math]. [math]\gamma, ¬A, ¬\alpha[/math] agree with 1). [math]B, ¬\beta[/math] are happy per 2). Since C is false, we require that all three of [math]¬\alpha, \beta, \gamma[/math] are true per 3)-5), and they are. Happy solution and consistent problem.

One error in the post that you replied to: the penultimate sentence is a misrepresentation (I brainfarted the conditional), mistaking a false->true situation, or a false->false situation (which are true) for a true->false situation (which is false).

Notice that in the post itself, I wrote first that [math]¬\beta[/math] is true, immediately contradicting myself by asserting that [math]\beta[/math] is true. Happily this doesn't matter as we instead should have said that the things in the RHS's of 3)-5) are "free". And indeed, two of them are true and one of them is false upon review, but it doesn't matter because all three conditionals evaluate to true, and the thing holds of course. We regret the error.
