Alright, if Jow Forums is full of geniuses (as all IQ survey threads seem to indicate)...

4 options, 1 of which is correct.
That's a 1/4, or 25%, chance at getting it right by random pick.

Yes, but there are two that say 25%. If 25% is the correct answer, then it's a 50% chance of getting it right by picking at random. However, that means that 25% is incorrect and therefore it's also impossible for it to be 50%.
It's also not 0% because it's possible to pick 0% randomly, making the correct answer 25%, which would make it 50%, which would make it 25%, and so on and so forth. It's a paradox.

How do we know if any are right? What if they're all right?

What's 2+2?
A. 5
B. 21
C. 7
D. 3

See, they're all wrong.

What's 5+4?
A. 9
B. 9
C. 9
D. 9

Now it's 100% chance to get right by picking at random

None of them are right. If you pick one, the answer changes.

What is missing here is the definition of correct. What do you consider correct? An logically sound answer to that question or trying other much more useful things?

0% answered deliberately with the knowledge that there is no one correct answer if picking randomly. In this case 0% is only a conscious answer, it would not work as a randomly picked answer. This question does not task you with randomly answering yourself.

Checkmate

p(25%)=.5
p(50%)=.25
p(0%)=.25

The probability of choosing any answer doesn't match the probability of the given answers. It seems kind of like selecting a truth value for "This statement is false".

In the book "Laws of Form", that statement is described as having an "imaginary" truth value. It is equated to the mathematical expression x^2+1=0, where x evaluates to sqrt(-1), or i. Even so, since "i" isn't an option, there is 0% chance of selecting it, sending you back to the loop.

Another way to look at it might be to say that the answer oscillates between the three. Which might be where you could get 33%.

that would mean there is a right answer making it 25%, this making it 50%...

I think ''B'', because half (50%) of the answers are ''25%''... right?

B.
Theres zero correct answers which means c is correct which mean a and d are correct which means b is correct. B final answer

This is an edit of the original where you have the following options:
A) 25%
B) 50%
C) 33%
D) 25%

Because you can't pick A and D, C would be correct.

After this picture was edited, however, both A and D stay crossed out.

It can't be 0% as well however, since by picking it and being right, your chance would be above 0% , so it's not C either.

We're left with B) which implies that picking between A and D and only one of them being taken as correct by the computer, your chance to answer would then be 50%.

C.
because you lose anyway, if it's random you don't choose C. and (You) wont be correct

en.m.wikipedia.org/wiki/Paradox

checked

alright brainlets i will teach you something.the answer is there is no answer
not every question in life has an answer, that is the most cruel truth of all

A and D cross each other out.

You're left with B and C. a 50% chance by default.

The answer to B is 50% so it would be 100% correct to choose B
dum dum

So it's 12.5%?

which answer is only 80% correct, silly willy?

the right answer when accounting for randomness is undefined since its an if-then statement, not any fixed percent. it is unanswerable when randomly guessing. the answer of 0% is given deliberately without guessing thereby not meeting the requirements of the paradox

>brainlets

none. B also cannot be 100% correct because B is 50%, so in either case it would be false.
there is no answer. not all questions have answers. there are some things we will never know in life. that is the answer

This guy gets it. There's no right answer.

cant be any
lets start with 25% - it would have been an actual answer if it wasnt for TWO possibilities with 25% as an answear.
50% then? No. there is only answer with such poercentage menaing you have 25% of picking it. it doesnt match.
so it must mean that 0% is correct!
well, no... because you can pick it at random with 25% chance. again, incorrect

Shit I've got it
It's C
The actual answer should be 33%, but since that answer isn't there, it must be C

Damn no wait that doesn't work
garbage trick question

If the answer was C, then C would be 100% correct, not 0%, a wrong answer either way

I JUST REPLIED THAT TO MYSELF
READ FAGGOT

>replying to yourself
oh nonono ahHA HAHAHAHAHAHAHAHAAHAHHAAHAAAHAHAHAHAA

if you take a significative sample of aleatory answers, each alternative gets a 25%, so either A or D are the right answers

just take into account that despite both A and D have a 25%, they're actually different answers

0%
cause whatever answer I pick, it's wrong
why are brainlets struggling with this?

but you have 25% chance of picking C

>one isnt equal eins, because the first one was written in english and the second in german

but C is wrong in the context of randomness
you can't pick a correct answer at random
so 0% is the right answer, because you don't pick the actual answer at random

25%, the numbers under the letters meaningless without the question?

>because you don't pick the actual answer at random
what? no! what is the difference between picking C at random and picking it consciously? i mean the answer has to be the same for both answering consciously and randomly. 0% chance at random means you cant draw this answer. but you can and chance of it is 25% - this is a paradox

if the chance for picking C is 25% it means C is not the right answer, neither is A,B or D so you have a 0% chance to pick the right answer at random, so C is the right answer, but only if you don't pick it at random
if you pick it at random it becomes a wrong answer, despite being the actual right answer

Smartest poster in the thread. There is no inherent right answer because the answer is picked randmyl ths owhbx

The chance that you'd randomly selected 25% is 50%, the chance that you'd select 0% is 25%, the chance that you'd select 50% is 25%.

For an answer to be correct, the chance of you choosing it randomly must be equal to the number specified in the answer. Therefore there is no correct answer (given that you are only allowed to choose A, B, C, or D), because no answer has a probability of being chosen that is equal to the number specified in the answer.

yes, i am aware of this. however does question "care" about the way you provide answer? the answer:
>"there is no valid possibility"
covers both random and decision
>"C"
covers only decision and stops being valid with randomness included. nowhere in the problem is written that you cant pick answer at random

>if you pick it at random it becomes a wrong answer, despite being the actual right answer
your answer needs a special boundary to stay valid

50% if you pick 25%
25% if others

Also 0 cuz this question is retarded

>your answer needs a special boundary to stay valid
yes
So the question either can't be answered or can only be answered, by deliberately engaging the question
However it also doesn't say anywhere that you have to answer the question, so not answering, is a valid answer according to your interpretation of the framework of the question
Also it says nowhere that you have to assign equal probabilities while picking a letter at random, which makes the answer even more ambiguous, for example you could assign 12,5% to A and D respectively so they are both accurate answers without contradiction, or you could assign 50% to B and it would be correct
So the answer all depends on your interpretation of the question

change D to something not mentioned before, like 30%, or change it to 50%. If both B and D say 50% there will indeed be a 50% chance of getting it right. If you, on the other hand, change D to 30% then A will be the only right answer, with 25% chance of getting it right.
You could also change A, then D will be right. Or you could change C to 50%, which will make both B and C right answers.
