If you choose an answer to this question at random, what is the chance you will be correct? a. 25% b. 50% c. 60% d. 25%

OpenStudy (zkoqmosii):

Hurts your eyes right?

OpenStudy (anonymous):

is this supposed to be confusing because my brain is hurting

OpenStudy (btaylor):

Dang. That's a good question.

OpenStudy (a1234):

The correct answer isn't in the choices. The correct answer is: 95.561230978546321468795%

OpenStudy (j2lie):

it is %0% because you might be wrong or you might be right.

OpenStudy (yttrium):

oops it's 50% A and D are both correct. because there are 4 choices in the question but there are 2 possible correct answer, and of course we are just to choose one among the choices

OpenStudy (anonymous):

^ what he said

OpenStudy (j2lie):

so 50% is wrong?

OpenStudy (btaylor):

Actually, it is 50% but for a different reason. Since A and D are the same, you must eliminate those because there cannot be two right answers. So, you are basically choosing between B and C, so there is a 1/2 chance.

OpenStudy (j2lie):

ok.

Peter Piper picked a peck of pickled peppers. A peck of pickled peppers Peter Piper picked. If Peter Piper picked a peck of pickled peppers, Where's the peck of pickled peppers Peter Piper picked?

OpenStudy (j2lie):

why 25%

OpenStudy (a1234):

It would be 25%, but there are two of them.

OpenStudy (j2lie):

no it's 50% because there is a possibility you might be right.

OpenStudy (zkoqmosii):

I'd rather not make your brains melt so I'll close it

OpenStudy (j2lie):

our brain can't melt.

OpenStudy (smored):

no it's ok

OpenStudy (a1234):

When you choose an answer to that question, you choose 1/4. 1/4 = 25%

OpenStudy (j2lie):

the number of choices doesn't matter. Because there are only two possibilities. Wrong or right.

OpenStudy (smored):

ther is no answer. ok, so first, 1 out of 4 is 25%, but since there are two answers with 25%, it becomes 50%. But, if the answer is b.50%, then there is only one answer so it becomes 25% (answer-ception)

OpenStudy (smored):

back and forth between 25% and 50%

OpenStudy (smored):

my conclusion is, there is no answer.

OpenStudy (btaylor):

I feel like if you made a tree diagram or something it would come out to a nice answer.

OpenStudy (j2lie):

ok fine it's 25%.

OpenStudy (smored):

no answer.

OpenStudy (j2lie):

or there is no answer.

OpenStudy (smored):

it is like this The statement below is false. The statement above is true.

OpenStudy (j2lie):

I'm right because I learned this before. it's 50%.

OpenStudy (smored):

yes, so you chose answer B) 50%. but then there is only one answer, so it goes back to 25%.

OpenStudy (j2lie):

are you dividing 50% by 2?

OpenStudy (smored):

no, there is only one answer choice that says 50%, so the chance of getting it right (answer B) is 25%.

OpenStudy (j2lie):

so you're saying the chance of getting the answer right is 25%. How do you know that?

OpenStudy (smored):

What I'm saying is that it goes back and forth. So after that, the probability goes back to 25%. But since there are two answers with the answer "25%" (A and D), the probability becomes 50% again. So there is no answer.

OpenStudy (j2lie):

the answer is 50%.

OpenStudy (yttrium):

@smored, your probability of getting the correct answer is actually 25% if and only if the choices are identical. So it would really be 1/4. In this case, there are 2 right answer. So among four choices, you have 2 chances of getting right. So 2/4 = 1/2 = 50% probability.

OpenStudy (j2lie):

thank you @Yttrium

OpenStudy (smored):

So your answer becomes B. 50% So the probability of getting answer B is 25%.

OpenStudy (j2lie):

you don't divide it.

OpenStudy (smored):

@j2lie , what is the probability that you are going to get the right answer (in this case, B)?

OpenStudy (j2lie):

actually you do.

OpenStudy (j2lie):

yes you'll get 50%.

OpenStudy (yttrium):

the answer is 25%, and the probability of getting 25% among the choices (A or D) is 2 out of 4, therefore 50%

OpenStudy (j2lie):

the choices matter?

OpenStudy (smored):

The chance of getting B is 25% (so answer goes back to 25%), then the chance of getting A or D is 50% (answer goes back to 50%). Then, the chance of getting B.(50%) is 25% (so answer goes back to 25%), then the chance of getting A or D is 50% (answer goes back to 50%). Now do you understand my explanation?

OpenStudy (j2lie):

i don't understand you cause you're saying 25%.

OpenStudy (smored):

What I'm saying is that there is no answer.

OpenStudy (j2lie):

there is an answer to every problem. There's no way there is no answer.

OpenStudy (smored):

Ok then. The answer is undefined.

OpenStudy (smored):

That better?

OpenStudy (j2lie):

you're being mean to me.

OpenStudy (smored):

No, your mind got blown.

OpenStudy (j2lie):

I'm leaving.

OpenStudy (smored):

Make sure you do not get a headache after this.

OpenStudy (j2lie):

why?

OpenStudy (j2lie):

I'm already having a headache.

OpenStudy (smored):

Well, good luck. Take an Advil or something.

OpenStudy (j2lie):

I can't take Advil.

OpenStudy (smored):

"how to relieve headaches" Google it

OpenStudy (j2lie):

by going to sleep.

OpenStudy (smored):

then you may go to sleep.

OpenStudy (smored):

btw, you said "I'm leaving." like 10 comments ago, so...

OpenStudy (j2lie):

yay.
