d

The question has some issue. If 0.25 is the answer to the question, uniformly picking among a) to d) would have a chance of 0.5 guessing it to be 0.25(picking a) or c)). But 0.5 is not the answer to the question!

If 0.5 is the answer, uniformly picking among a) to d) would have a chance of 0.25 guessing it 0.5 (picking d)), but 0.25 is not the answer to the question either!

So, my conclusion is that the question intrinsically has contradiction such that there is no answer.

would you care for explanation?

Mind says : A
But It cant be that easy for a interview

I think we need to calculate the probability, rather than choosing from the given options. The options look like part of the question and we are not required (and should not) choose the given values.
My answer:
Since there are three unique answers, each has 1/3 chance of being correct. Also (0.25) appears twice, so it has 1/2 probability of being chosen; the rest have 1/4 probability of being chosen. So,
P(0.25 is right answer and it is chosen) = P(0.25 is correct) x P(0.25 is chosen) = 1/3 x 1/2 = 1/6
P(0.6 is correct and it is chosen) = 1/3 x 1/4 = 1/12
P(0.5 is correct and it is chosen) = 1/12

P(choosing randomly and it being correct) = 1/4 x 1/3 = 1/12

we r choosing ans randomly then d probability wud be 1/4...(don.'t care about d options)

it is "D"
i.e .50 probablity...
as .25 is probablity of correctly guessing the answer.... and .25 is twice in the options... :)

awesome question...it is a brain twister rather than a teaser.(ref tongue twisters :P)

simply mind baffling...i'll skip the question :P

50%.

Its asking for a probability. Before answer,
Is there a right answer to the question? if no, then 0 %.
If it was randomly choosen, its either right or wrong, thus 50%.

Well, it actually depends on how you want to view the question. If you regard as the numbers being the options, then yes D is the correct answer.

But let's say that the answer randomly chosen is the actual letter in the set {A, B, C, D} and we do not care about the number. Then, actually, the answer would be 25%.

If the answer is .25, then the probability of getting .25 randomly is 50%. So that's not it. If the answer is .5, then the probability of getting .5 randomly is 25%, so that's not it either. .6 is not the answer for the same reason. I don't get it.

Ans can be right or wrong,probability for getting it right is always 1/2 means 0.50.
So that 'd' is correct option.

Easiest Question Ever....:)

Good question :)
