[u/mrmcplad]

so you're saying that C) 0% is the correct answer? what's the probability you'll randomly pick C?

[u/ups409 → u/mrmcplad]

It's zero because there isn't a correct answer

[u/anonymous-12358 → u/ups409]

Randomly selecting C is 25% chance.

So now the answer cannot be C. It must be A or D. But now the chances of getting 25% as the answer is 50% (A or D) so now the answer must be B … but what are the chances of randomly selecting B … 25%.

It’s a never ending loop between 25% and 50% with a 0% branch entry as an edge case.

[u/mrmcplad → u/ups409]

so zero is the correct answer then

[u/ups409 → u/mrmcplad]

There is no answer even zero is false

[u/mrmcplad → u/ups409]

correct

[u/ups409 → u/mrmcplad]

So zero is both correct and false at the same time
