is the answer B? why or why not?

>>8015337
you should atleast put the answer in the god damn choices

>>8015337
does not compute

>>8015337
If there's 4, but two are the same, then it's 3 answers
1/3
No possible answer up there

this question is self-referencing it makes no sense

unintelligible question...

>>8015346

why would a self-referencing question make no sense? here's a self-referencing question with a clear answer:

"is this question written in English?"

> yes

4 choices means you have a 25% chance of choosing the right answer. 25% is listed twice. Now you have 2 chances of picking the right answer. This doubles your chance to 50%. Are you people actually in any advanced classes or do you all just come here to parrot whatever episode you have recently seen on the big bang?

>>8015368
but you'd have 33% chance to get the right answer it doesn't make much sense

>>8015368

so it's B?

0%

>33%
Where are you getting this number? Show your work.

Let's help you break it down. You have 4 options to pick. 1/4 = .25 or 25%. That answer is listed twice. So now we know if we choose randomly we have a 2/4 chance to get it right. 2/4= .50 or 50% .

Did that help you?

>>8015402
There's 3 different answer it can't be 50%

>>8015337
Stop reposting your bait.

>>8015368
>>8015402

But if the answer is 50%, which is B, it's only listed once. Now you're back at 25% being the correct answer, which is A and D. But it's listed twice. So now the answer to the question is listed twice, which gives you a 50% probability of randomly guessing it correctly. So now the answer is B. Which is listed once, which gives you a 25% chance of answering it correctly, which is A and D which is listed twice...

Now do you see how it's an unanswerable, trick question, you simple-minded moron?

>>8015434
The answer to the question and the correct answer to the % are not related. It is you who is the simple minded one my friend. Once the answer is solved you don't revert it because your small brain can't make the theoretical leap.

>>8015337
C because it avoids the paradox.

>>8015337

If you flip a coin to pick between A and B, the answer is B.

>>8015337
>C) 60 %
It should read 0 %. Otherwise 0 % could be the true answer.

>>8015882
>The answer to the question and the correct answer to the % are not related

Incorrect. They are intrinsically related due to the wording of the question. That's precisely what makes it an unanswerable question. You're just a fucking moron who didn't realize that to begin with and now you're trying to justify your retardation. Sorry man.

U guys are formated by school...
it is 1/infinity

>>8015337
the correct answer isnt 50% or 25%

the correct answer is either a,b,c, or d

the content of the answer does not matter

so its 25%

There are 2 answers the same which makes it 50% but it cant be 60% so 2/3

>>8016400
agree

>>8016427
It's wrong though. Anon assumes that only one answer can be correct, but that is nowhere stated. If all four answer were 100 % then that would be the answer. If 3 of them were 75 %, then that would be correct, too. But in this scenario, none of the options match their probability, so there is no answer.

>>8015337
The answer is False

>>8015337
If A is true, then so is D -- making B the correct answer. Now since B is one of four choices, it suggests that the probability of selecting a choice at random is 25%, and therefore B and C are wrong. This loop is broken and there is no correct answer given the provided choices, unless there is an E) option which states "this question is a logical fallacy and is structured in such a way that there is no answer."

>>8016193
Good god thanks for the only intelligent answer in this thread

>>8015367
Just because it works out for a specific case does not mean it works out generally.
Some posit that a self-referencing sentence or question isn't even a complete thought. Here's what I mean.
>This statement is false.
Which statement are we talking about?
>This, "this statement is false," is false.
...Which statement are we talking about?
>This, "This, 'this statement is false,' is false," is false.
...Which statement are we talking about?
And so on and so forth. There's no concrete way to express "what" exactly the statement is talking about. You just know from intuition that the person saying it is trying to be a cheeky cunt.

>>8015346
You're no fun.

B is the correct answer

The answer is 0%

>>8015337
Given that there is one right answer and that answer may appear up to n times in the multiple choices provided, the answer would be n/m where m is the total number of answers. For the average four-point question we have anywhere from 0 to 4 randomly chosen right answers, making the total set of all possible correct probabilities {0, 1/4, 1/2, 3/4, 1}. Counting each of these answers we find that 0 occurs 0 times, making the question unanswerable at n=0, 1/4 occurs twice, making that answer wrong at n=1, 1/2 occurs only once, making the n=2 answer wrong as well, and n=3 quality answers occur as often as n=0 answers.

Thus, the correct choice has not been given.

Correct answer is suck my dick, nigga

>>8016469
I went through the same reasoning

>>8015342
You fucking idiot. There are two identical answers, your odds are 25% per unique, and 50% for the double. Saying there is 33% chance for each is retarded

There is no metric given for correctness, this question is shit

The answer is an infinite loop. You have a 1/4 chance of answering a 4 answer question right at random, but 25 is there twice so you now have a 1/2 chance, but you only have a 1/4 chance of guessing 50.
The answer isn't 33% because 1/4 and 1/2 can't both be correct at the same time.

>>8015337
The question contradicts itself, if the answer is 25, then there is a 50% chance of picking it at random in which case the answer is not 25. If the answer is B or C (50% or 60%) then there s a 25% chance of you picking the answer in which case the answer is no 50 or 60, so none of the answers are correct

>>8016556
But if 0% was one of the choices would that change anything

The answer is C because you chose randomly and happened to pick that one.

Is there a rule for excluding these kinds of questions from the collection of valid questions?

Since the question is self-referential, one is reminded of Russell's Paradox which talks about sets containing themselves.

Maybe one could try to translate into a formula to see where the problem lies.

.0625

reason: each choice has a 50/50 chance of being correct

so multiply the probabilities together
voila
.0625


i trust system 1

So, the question can be reduced to solving the following equation:

Y = P(X = Y)

where Y \in [0, 1], P is the uniform measure defined on {a, b, c, d}, and X is a random variable on said set with the following definition:

X(a) = 0.25
X(b) = 0.5
X(c) = 0.6
X(d) = 0.25

It can be seen easily that there is no Y for which this equation holds.

However, there is an important difference between these formulations: While the search for Y is a well-defined problem that raises no questions, the original formulation of the problem is considered a paradox.

>>8021338
After considering another set of values I've realized that this is actually not a correct model of the question because it gives rise to another paradox:

a) 2/3
b) 2/3
c) 1/3

>>8015411
it's the same as having two differents right answers :-)
