You can never answer this question correctly. If the correct answer is 25% there’s a 50% chance you guess correctly but that would make the 25% wrong.
But if the answer is the 50% then it implies that 25% is correct which implies that 50% is wrong.
We reach a contradiction for both 25% and 50% making the correct answer to make the whole statement truthy 0%.
Any answer is correct as long as you don’t pick it at random. I’d choose (a) because I’m too lazy to read the other options
This can also be used a great example of proof by contradiction: There is no correct answer in the options. Proof: Assume there was a correct answer in the options. Then it must be either 25%, 50% or 60%. Now we make a case distinction.
(A) Assume it was 25. Then there would be two of four correct options yielding in a probability of 50%. Therefore 50 must be the correct answer. -> contradiction.
(B) Assume it was 50. Then there would be one of four correct options yielding in a probability of 25%. Therefore the answer is 25. -> contradiction.
© Assume it was 60%. Since only 0,1,2,3 or 4 of the answers can be correct the probability of choosing the right answer must be one of 0% 25% 50% 75% or 100%. -> contradiction.
Because of (A), (B) and ©, it cannot be 25, 50% or 60%. -> contradiction.
Cheeky answer - the correct answer is a superposition of 25% and 50%, thus you answer it as a multiple choice question

My client renders this as ( c )
I would think a b c d so 25% O he made a mistake znd forgot to take the bubble answer out. Now we only can pick between aord b c so it would be 33%
Seems my logic is wrong iff i read the rest
Great! I’ll hand this to my daughter to annoy her co-students who struggle with probabilitiy ;-)
It was only the next day that I returned to this post realising that “this question” isn’t even defined.
0%
The only winning move is not to choose
Yeah option b should definitely be 0% for added fuckery
The answer is clear
When in doubt, C it out.
Thanks for making me laugh all alone in my car before heading in to work. I wish I could give you an award. Cheers!
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.
🤯
I choose 75%
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
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
You think like I do. Bet you test well.
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.
But some tests award bonus points if you get the thrown out question right by answering what it should have been!
Fair enough
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.
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#
No. The scenario asks you to consider a random selection, but the solution in that case is a certainty.
Loaded dice
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.
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.
It’s still providing a correct explanation to people, I guess
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
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 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 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
Y’all have got to stop this shit. Real people use real grammar.
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

Huh. I think it was just the web version of Lemmy. Weird choice by the Lemmy devs.
