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.

[–] moakley@lemmy.world 15 points 1 day ago (1 children)

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.

[–] moakley@lemmy.world 4 points 1 day ago (2 children)

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!

You chose A, C, and D, so you have a 100% chance.

Nice logic; poor reading comprehension.

[–] moakley@lemmy.world 16 points 1 day ago (1 children)

Does better reading comprehension get you a better answer?
