### I really liked this one (the followup)

I recently wrote about an interesting question (not Oracle related!). I found the question interesting because it reminds me of so many questions I actually receive about Oracle. They are vague, incomplete, ambiguous, confusing at times.

The question I referred you to fell squarely in that category. It was:

They are missing the correct answer in the list! And adding the correct answer would change the answer - so that it might be incorrect as well. Meaning - there is more missing here than supplied. You don't stand a chance of answering the question at all.

I put forth that the answer is "e) none of the above" - making the right answer "20%".

Looking at the problem, if you assume the right answer is 25% - because you have a 1 in 4 chance of selecting any one of the items - the probability you will get the right answer randomly is 50%. So, it cannot be 25% - if it were - it would be 50% (confusing, yes).

Moreover, if you assume 50% is correct, then the right answer is 25% - because the chance of picking 50% is 1 in 4.

If you assume 60% is correct - well, I don't know what to say.

The question itself seems to somehow affect the answer - the act of answering the question changes the answer. Sort of like when you run a program in the debugger and it works perfectly - but when you run it standalone it crashes (that has never happened to me, nope, not a chance...).

So, my answer is "e) none of the above"

The question I referred you to fell squarely in that category. It was:

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%
