Choose an answer randomly

My stats is rusty, but I'm saying 1/3.

If the answer is 25%, then you have a 1/2 chance of picking it. There is also a 1/3 chance that 25% is the right answer, so (1/3)*(1/2) = 1/6
If the answer is 50%, then you have a 1/4 chance of picking it. There is also a 1/3 chance that 50% is the right answer, so (1/3)*(1/4) = 1/12
If the answer is 60%, then you have a 1/4 chance of picking it. There is also a 1/3 chance that 60% is the right answer, so (1/3)*(1/4) = 1/12

(1/6) + (2/12) = (1/3)

So I say you have a 33% chance of getting it right. But I have been known to be an idiot.

I will now answer C to all questions which I do not know any part of in those Scantrons.
 
It's a great question that really gets you thinking! But it's impossible to answer because: in order to know the 'chance of being correct' you need to know exactly 'how many correct answers are there?'

If you answered the first question (what are chance of being correct) then you - in your own mind independant of the question - already determined what the correct answer is. Which you don't know.

It is a trick question, as required logic (math!) is missing, yet you're forced to try and answer logically.

If 25% was the correct answer, then randomly it was 2 of 4.

If 50% or 60% was the correct answer, then randomly it was 1 of 4.

No one can say "the answer is...".

Someone can say "If the correct choice is ____ then the answer would be ____. However, the correct choice could be ___ and in that case the answer would be ___."
 
I choose not to choose.


reminds me of the catch 22 regarding the bible. in a nutshell gods greates gift to man, was freewill, the right to choose.

if you believe in god, and be good, you go to heaven.. if you are bad, you go to hell.
if you dont believe in god, you go to hell.

If i am truly given a choice, and choose not to belive, why should i be punished for that choice ?
 
I'm going with B) 50%.

You have a 1 in 4 chance of randomly picking the right answer (25%), But the chance of picking 25% at random is 50%.

Ahhh, but grasshopper - the answer CAN'T be 25 percent if you have a 50 percent chance of picking it!!!!

My brain hurts :(

I was sort of ignoring the actually percents (wrongfully, I see now), and just calculating the stats of choosing correctly, if a and d were the same.
 
The answer is 1/2. 4 options, thus the correct answer is "25%" and there are two "25%" among the four options.

Bit of a mindf*** cause you can easily confuse the question that's being asked with the multiple-choice format. You're not asked to pick one of the four answers, merely to compute the odds that you'll land on the right answer if you randomly pick a letter (A, B, C, D) out of a hat.

1 in 2.

Now of course, if you are asked to express the answer to the question by picking one of the four answers, you can't answer definitively.
