As I've gotten older I understand math better, it's more logical, but when I was in school no one could teach me either garet82, so don't feel bad. :)
 
I'm an engineer and use crazy math all the time. When I was a kid I was horrible at math. But that was because I didn't try and was not serious about school. However I loved taking stuff apart and building things. When I grew up I realized that if I want to do that stuff for a living I better learn math. So I relearned practically all math starting from algebra 1 all the way to advanced calculus at community college, and learned to love it and be good at it.

Math is very logical. There are always right and wrong answers. Unlike life. Also math is God's language of the universe. What is not to love? Math is like a puzzle that is waiting to be solved. As is the universe.
 
Math is lovely because there is one solution(usually), and more often than not there are multiple ways to arrive at the solution.

assuming the right answer is in the set { .25, .5, .6 },

and that by "randomly" it is meant "uniform distribution"

we pick:
.25 with prob. 1/2
.5 with prob 1/4
.6 with prob 1/4

therefore:
if .25 is correct, we pick it with probability 1/2, so A and D are incorrect.
if .5 is correct, we pick it with probability 1/4, so B is incorrect.
if .6 is correct, we pick it with probability 1/4, so C is incorrect.

since A, B, C, and D are incorrect, if we choose an answer randomly to that question, the probability we are correct is 0.

Its a paradoxical question. I think its meant to be read as if the probability to randomly guessing the right answer to a 4-choice question is in general always 25%, since there are 2 options A,D that are 25% there is a 50% chance you would pick A,D, thus correct answer is B

it's meant to assume the correct answer is uniform over {A,B,C,D}, not over {.25, .5, .6}

see how important it is to clearly define the space you work in?!

ahahaha ;) math jokes are never funny when you prove they are funny.

Here's what I see
the correct answer was 25% until another 25% answer was added
which then makes the chances 2/4 or 50%
but now since (B) 50% is the only correct answer, this brings the probability back to 25% again so then the correct answer is suddenly no longer (B) at 50%.
Therefore each time a correct answer is added... the probability increases by the amount of correct choices offered thereby nullifying the last probable answer.

So, Yes it appears to be a paradox.

" These aren't the decimals your looking for "

- sorry,that's all I got.
 
I like math because it tastes good :p

I wish I understood difficult Maths (yes we add an s :p)...if only for the reason that I could sound smarter than I am :DD
