If you found a genie that only offered one wish, but he only answers wishes on odd numbers, and if its even he kills you, and you found him on a zero, would you ask?
Well that’s easy. I would wish for three more wishes.
See, zero is either both odd and even, or it is neither. If it’s neither, no harm no foul. If it’s both, he can kill me, but he also must grant my wish, which is to give me three more wishes (as any upstanding wisher would wish for). With one of those wishes I can wish that he does not kill me.
