If you’re choosing the answer, then there is 100% chance of being correct. Since none of these answers is 100%, the chance is 0%.
That logic would only hold if I wasn’t dumb as rocks.
🤯
It’s annoying that 25% appears twice. How about these answers:
a) 100%
b) 75%
c) 50%
d) 0%
Thanks for making me laugh all alone in my car before heading in to work. I wish I could give you an award. Cheers!
This is a conundrum wrapped in a turducken, swaddled in nesting dolls.
lol chill out there buddy it is only self-referential once. maybe twice.
I’m not certain, I think it’s an infinite loop.
I.E. If the answer is 25%, you have a 50% chance, if the answer is 50%, you have a 25% chance, if the answer is 25%, you have a 50% chance…
The only way out is to choose 60% to accept defeat
Haha, I think they should have made that option 0%, to further the paradox
Yeah, that’s right. https://en.wikipedia.org/wiki/Paradox
What’s the correct value if the answer is not picked at random but the test takers can choose freely?
All answers are correct then.
It’s probably graded by a computer, and a) or d) is a fake answer, since the automated system doesn’t support multiple right answers.
I’m going to go with 25% chance if picking random, and a 50% chance if picking between a) and d).
If it’s graded by a human, the correct answer is f) + u)Many systems do allow multiple correct answers.

Damn hitchhikers.
But what’s the question?
how many roads must a man walk down?
What is six times nine
Close, but nah, it’s the meaning of life
nuh uh, it’s the answer. to life, the universe, everything! Um, but what’s the question?
The question is malformed and the correct answer isn’t listed in the multiple choices. Therefore the correct answer is 0%
If only one of the 4 options said 25% would it still be malformed#
33% innit
iis
It is 33% if the answer itself is randomly chosen from 25%, 50%, and 60%. Then you have:
If the answer is 25%: A 1/2 chance of guessing right
If the answer is 50%: A 1/4 chance of guessing right
If the answer is 60%: A 1/4 chance of guessing right
And 1/3*1/2 + 1/3*1/4 + 1/3*1/4 = 1/3, or 33.333…% chance
If the answer is randomly chosen from A, B, C, and D (With A or D being picked meaning D or A are also good, so 25% has a 50% chance of being the answer) then your probability of being right changes to 37.5%.
This would hold up if the question were less purposely obtuse, like asking “What would be the probability of answering the following question correctly if guessing from A, B, C and D randomly, if its answer were also chosen from A, B, C and D at random?”, with the choices being something like “A: A or D, B: B, C: C, D: A or D”
B.
This is a multiple choice test. Once you eliminate three answers, you pick the fourth answer and move on to the next question. It can’t be A, C, or D, for reasons that I understand. There’s a non-zero chance that it’s B for a reason that I don’t understand.
If there is no correct answer, then there’s no point hemming and hawing about it.
B. Final answer.
I love this, it shows how being good at (multiple choice) tests doesn’t mean you’re good at the topic. I’m not good at tests because my country’s education system priorities understanding and problem solving. That’s why we fail at PISA
Entertaining response but I disagree.
I’m going to say that unless you’re allowed to select more than one answer, the correct answer is 25%. That’s either a or d.
By doing something other than guessing randomly (seeing that 1 in 4 is 25% and that this answer appears twice), you now have a 50% chance of getting the answer correct. However, that doesn’t change the premise that 1 in 4 answers is correct. It’s still 25%, a or d.
That’s an interesting perspective. The odds of correctly guessing any multiple choice question with four answers should be 25%. But that assumes no duplicate answers, so I still say that’s wrong.
I’m going to double down and say that on a real life test, this would likely represent a typo. In such case, I think you could successfully defend a 25% answer while a 60% answer is just right out the window, straight to jail.
The typo makes the answer incorrect. The whole question would need to be thrown out.
Fair enough
You think like I do. Bet you test well.
You chose A, C, and D, so you have a 100% chance.
Nice logic; poor reading comprehension.
Does better reading comprehension get you a better answer?
No of course not, but the question is more important to the answer than the “correct” answer.
Not in a multiple choice test
This isn’t a test. It’s a logic puzzle.
It’s not a puzzle. It’s just wrong.
“Which of the following is a mammal:
A) rock
B) time
C) verb
D) Enui”Is not a puzzle.
Based on previous guy’s logic: D.
I know A, B, and C are definitely wrong, but I’m not sure I fully understand D. So it’s D and move on.
Reality is I make a note and discuss with the teacher if they don’t notice themselves when tests come back.
This is a self-referential paradox — a classic logic puzzle designed to be tricky. Let’s break it down:
Step-by-step analysis:
-
How many choices? There are 4 possible answers, so if we pick one randomly, the chance of picking any specific one is 1 in 4 = 25%.
-
How many answers say “25%”? Two.
-
That means the probability of randomly choosing an answer that says “25%” is 2 in 4 = 50%.
-
But if the correct answer is 50%, then only one option says “50%” — which is ©. So the probability of picking it at random is 1 in 4 = 25%, contradicting the idea that 50% is correct.
-
If the correct answer is 25%, then two options say that — a and d. So the chance of picking one of those at random is 50%, not 25% — again a contradiction.
-
Similarly, if 60% is correct (only one option), then the chance of picking it randomly is 25%, which again makes it incorrect.
Conclusion: Any choice leads to a contradiction. This is a self-referential paradox, meaning the question breaks logical consistency. There is no consistent correct answer.
Chatgpt ass answer lmao
haha yeah, I knew it at the “let’s break it down:”
I was like… I know this voice…“Conclusion:” was the final nail in the coffin
The motivation to do so confuses me. There’s no karma to farm here.
It’s still providing a correct explanation to people, I guess
Why not? Here upvotes do the same as karma in reddit. Absolutely nothing.
Eh. On Reddit, karma was intended as an indicator of quality and authenticity. It was heavily flawed and abused by bots and propagandists.
Got it right though
The © gave it away
That’s whatever browser or app you’re using. It rendered as © for me… Bracket, c, bracket
Well, parenthesis, and parenthesis, but yes
Parentheses can also be called (round) brackets, especially in the UK
ah, TIL, thanks
The em dash is a dead giveaway as well
Y’all have got to stop this shit. Real people use real grammar.
I used to use em dashes all the time and now I find myself rethinking my writing styles because of people like you and it’s obnoxious.
AI has put me off writing lists.
I try to use em dashes when I can, but I think they’re used wrong in the comment above (IIRC they’re not supposed to be surrounded by spaces, but I could be wrong). What tips me off is the unambiguously “LLM” narrative voice and structure (“let’s break it down”, followed by an ordered list). Not that a human can’t type that, but sometimes it seems like ChatGPT is incapable of spitting out words in any other structure.
You’re right, en dashes would have been fine there. Em dashes don’t get spaced—and have specific grammatical uses too.
counter—point ; noone will accuse u of being a Ai if your grammer is shitte in a precise mannor , thou they will gouge ther I:s out when trying to reed it
actually come to think of it, aren’t homophones/alternate spellings a pretty good way to avoid AI stuff? since they have absolutely no concept of the sounds words make. though i suppose it’ll only work until the models get trained on that data…
I use em dashes all the time, but I don’t put a space on either side—I feel like that’s not the correct way to use one. If it is, I don’t wanna be correct.
I concur with this.
Heyo yee em—comrade
Can’t tell if serious because entering ( c ) without the spaces is © in Firefox and other browsers.
Is it because the other letters don’t have brackets? I don’t use AI to know if that is a thing.

…so like, which one you picking?
E.
I would think that if you truly pick at random, it’s still a 25% chance no matter how you cut it

You had to show off, huh
The comment - which isn’t edited - uses
(c).Whatever client you use replaces/renders © [bracket c bracket] as ©.
Huh. I think it was just the web version of Lemmy. Weird choice by the Lemmy devs.

Paradoxes aside, if you’re given multiple choices without the guarantee that any of them are correct, you can’t assign a chance of picking the right one at random anyway.
C, which means A or D, which means C, which means…
Lisa stays home?
It’s 0%, because 0% isn’t on the list and therefore you have no chance of picking it. It’s the only answer consistent with itself. All other chances cause a kind of paradox-loop.
I agree with 0% but disagree there’s any paradox - every choice is just plain old wrong. Each choice cannot be correct because no percentage reflects the chance of picking that number.
Ordinarily we’d assume the chance is 25% because in most tests there’s only one right choice. But this one evidently could have more than one right choice, if the choice stated twice was correct - which it isn’t. So there’s no basis for supposing that 25% is correct here, which causes the whole paradox to unravel.
Now replace 60% with 0%. Maybe that would count as a proper paradox. But I’d still say not really, the answer is 0% - it’s just wrong in the hypothetical situation posed by the question rather than the actual question.
Correct - even if you include the (necessary) option of making up your own answer. If you pick a percentage at random, you have a 0% chance of picking 0%.
I see 25% twice so my bet is on 50%.
But 50% only appears once, which would make the answer 25%.
