Is the problem to be solved mathematically or logically? Which class does this come from? No context so cant say for sure LOL.

It is actually quite simple..
"
If you choose an answer to this question at random, what is the chance you will be correct?".
First of all, you need to ask yourself, "what question do I need to answer?" Else you can't calculate/estimate the chance you will answer it properly.
Lets focus on the last part of the "problem" as I choose to call it. "
what is the chance you will be correct?" That's a fair question. Now lets find out, what we need to do correctly. Lets have a look at the first part of the "problem". "
If you choose an answer to this question at random". All I can say is, what question... there is none.. ;)
Hence you can't answer it. Face it, you guys got fooled
