Default Re: Questions on target distribution and others of lecture four

If that dependency is not deterministic and we have different y's that may occur when x occurs, we have a target distribution P(y|x). The fact that it depends on x is inherent, as a different x would result in a different distribution of y's.
Thank you for your intelligible answer. And what about the second and the third one?
