That kinda makes sense, but here's the typical consensus...
Randomness means each outcome is equally likely to happen. Given 4 possible outcomes, each is 25% likely to be chosen. Two of the answer choices (A and D) have the correct 25%. However, you don't choose these for answers, because the question is asking how likely it is to choose a correct choice at random from the four. 2 correct choices out of 4 gives B, 50%.
It's a real ***** question because the answer choices include two different classes of observations.

kuchikirukia (01/19/2014) [-] So A and D are correct, therefore B is correct.
That's three correct answers. So why did you pick B?

Its really not that hard, the answer is B) because since normally it would be 25% (A or C) that means you have a 50% chance of choosing the right answer which would be 25%.

bushingenna (01/19/2014) [-] if you think about it the entire question makes zero sense.
If you chose to answer the question AT RANDOM, then you aren't really making a descision you are basically closing your eyes and picking A B C or D out of a hat. The fact that they then ask you to answer that same question makes no sense since by answering it, you would not be doing it randomly.

erikus (01/19/2014) [-] The answer would be C).
Because if you choose an answer from 4 options, that'd be 25% of choosing the correct one.
But being 2 answers the same, you are left with 3 options.
If you choose one at random, you'd have a 33.333...% prob you are right.
33.333...% Isn't an option, therefore, only C) is correct, as these answers don't contain the right one.
I might have gone full retard here but no regrets.

kuchikirukia (01/19/2014) [-] If C is the correct answer then the correct answer is, "25%," as there's a 1 in 4 chance of getting C. But C says 0%
Also, if it said 33.33% instead, it would still be a 25% chance. So that wouldn't be right.

rubiksdodecahedron (01/19/2014) [-] well since there are two that say the same thing neither can be right therefore you are actually down to 2 options and thus a 50% chance meaning that B is the correct answer

sirslowass (01/19/2014) [-] This can't be answerd correctly. If you answer A or D the right answer will be B, and if you answer B the right answer will be A or D.

kuchikirukia (01/19/2014) [-] Except there's a 25% chance of answering C, so that's A or B.
