  It’s a bullshit question

    C should be: A and/or D.

    There, now its a bafflingly bullshit question.

  All right, let's break this down.

  For this question, for these available answers, choosing at random:

  First glance says the correct percentage is 25%. There are four answers, you get to pick one.

  However, two of the answers are 25%. This means you have a 50% chance of picking an answer that's right.

  Which makes the correct answer C: 50%.

  But there's only one answer that's "50%", so you have a 25% chance of picking that one.

  Which makes the correct answer "25%", so you have a 50% chance of picking that one.

  If we consider that "two answer" equation, we can then consider the correct percentage to be "37.5%" -- halfway between 25% and 50%. That makes the correct answer from the available answers to be B: 0%.

  And you have a 25% chance of picking that one at random. So we go back to the beginning, where the correct percentage is 25%.

  I think we need to get Matt Parker on this one.

    They don’t say that the random answer is chosen uniformly (though that is the norm in the field). If we relax that, then we’re putting a distribution on these where we want:

    P(correct with distribution (a,b,c,d)) = some value shown on A,B,C,D

    I don’t see any assumption that we will pick using that distribution, so I think this avoids the recursion.

    Unfortunately this has too many solutions. If you put a total of 0.25 weight on A and D, then the rest does not matter. If you put 0.5 weight on C, again the rest is irrelevant.

      You've added details that aren't in the question. It's like asking what are the odds of rolling a "one" on a 1d4, and then saying "Well, if it's not a fair 1d4, then ..."

    There is simply no solution. If you choose an answer as “correct” it is shown to be not correct, (not a 25% chance to choose 25%, not a 50% chance to choose 50%, not a 0% chance to choose 0%) showing there is no correct answer.

      There's always a solution. Even if it's "empty set".

    There’s also, I think, the weird fucky option were 75% sorta works because the 25% applies to choosing 50% and 50% applies to choosing 25% which means that as long as you don’t choose 0% you’re good?

  Use a life line to remove two of the wrong answers and break the logic loop.

  source

  • madjo@feddit.nl ⁨11⁩ ⁨hours⁩ ago

    Only choose the 50/50 life line if you never mentioned any of the answers as possible answers.

    What if you’re left with A and D though

      then the show is wrong, and you sue them if get say you’re wrong.

    • then_three_more@lemmy.world ⁨13⁩ ⁨hours⁩ ago

      I guess it depends on how 50/50 works whether that’s possible or not. Does it remove two wrong answers or does it leave you with one right and one wrong answer? Is light a wave or a particle? We’re getting into Schrödinger lifeline territory now.

      Then one of those is right, and one is wrong. Probably There’s a non-printing character in one of the answers that makes it parse as an invalid string.

  To answer this question correctly we need to use my favorite super power: pedantry. The meme suggest the rules of who wants to be a millionaire are in play, but that is not expressly stated. Furthermore we’re going to ignore our societal training at recognizing multiple choice questions because, again, we’re not given instructions.

  With these powers combined, the question is ambiguous as it doesn’t specify the set from which we are choosing. Using the 4 options below the question is an assumption. Therefore we have to conclude that we’re choosing from an infinite set of options, every possible decimal value from 0 to 100.

  The answer is an extremely small percentage, approaching zero.

  It doesn’t say for this question, so 25%

  • just2look@lemmy.zip ⁨1⁩ ⁨day⁩ ago

    If it isn’t for this question, then its unknown how many options you have for the question.

      As you say, the question presented to Fry doesn’t mention a question at all. Only an answer. So, you could make an argument that any answer could be the answer to something, and therefore you’d have to choose a 100% chance, which isn’t an option.

      On the other hand, it asks for the chance of “picking the correct one”, clearly meaning “the correct answer”. So, as there is no answer that is the correct answer to everything, the correct choice would be 0%, which is an option.

  Simpler version that fits comfier in my head:

  What’s the opposite of the correct answer to this question?

  • A) There’s no correct answer
  • B) There is a correct answer
