This is a self-referential paradox — a classic logic puzzle designed to be tricky. Let’s break it down:

Step-by-step analysis:

  1. 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%.

  2. How many answers say “25%”? Two.

  3. That means the probability of randomly choosing an answer that says “25%” is 2 in 4 = 50%.

  4. But if the correct answer is 50%, then only one option says “50%” — which is (c). So the probability of picking it at random is 1 in 4 = 25%, contradicting the idea that 50% is correct.

  5. 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.

  6. 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.

...so like, which one you picking?

The comment - which isn't edited - uses (c).

Whatever client you use replaces/renders (c) [bracket c bracket] as ©.

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

Got it right though

That's whatever browser or app you're using. It rendered as (c) for me... Bracket, c, bracket

[–] kautau@lemmy.world 0 points 2 days ago (1 children)

Well, parenthesis, and parenthesis, but yes

[–] cazssiew@lemmy.world 0 points 2 days ago (1 children)

Parentheses can also be called (round) brackets, especially in the UK

[–] kautau@lemmy.world 0 points 2 days ago

ah, TIL, thanks

The em dash is a dead giveaway as well

[–] Vespair@lemm.ee 0 points 2 days ago

Y'all have got to stop this shit. Real people use real grammar.

[–] Reyali@lemm.ee 0 points 2 days ago (1 children)

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.

[–] JacksonLamb@lemmy.world 0 points 2 days ago

AI has put me off writing lists.

[–] ProfessorProteus@lemmy.world 0 points 2 days ago (1 children)

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.

[–] anomnom@sh.itjust.works 0 points 2 days ago

You’re right, en dashes would have been fine there. Em dashes don’t get spaced—and have specific grammatical uses too.

[–] Rai@lemmy.dbzer0.com 0 points 2 days ago (1 children)

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.

Heyo yee em—comrade

[–] spankmonkey@lemmy.world 0 points 2 days ago* (last edited 2 days ago) (1 children)

Can't tell if serious because entering ( c ) without the spaces is (c) 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.

haha yeah, I knew it at the "let's break it down:"
I was like.. I know this voice....

[–] josefo@leminal.space 0 points 2 days ago

"Conclusion:" was the final nail in the coffin

[–] nickwitha_k@lemmy.sdf.org 0 points 2 days ago (2 children)

The motivation to do so confuses me. There's no karma to farm here.

[–] Siegfried@lemmy.world 0 points 2 days ago (1 children)

Why not? Here upvotes do the same as karma in reddit. Absolutely nothing.

[–] nickwitha_k@lemmy.sdf.org 0 points 1 day ago

Eh. On Reddit, karma was intended as an indicator of quality and authenticity. It was heavily flawed and abused by bots and propagandists.

[–] smeg@feddit.uk 0 points 1 day ago

It's still providing a correct explanation to people, I guess

[–] MrShankles@reddthat.com 0 points 2 days ago

I would think that if you truly pick at random, it's still a 25% chance no matter how you cut it
