I want to fill

\begin{tikzpicture}[line cap=round,line join=round,>=triangle 45,x=1.0cm,y=1.0cm]
\clip(-2.3,-2.3) rectangle (2.3,2.3);
\draw [rotate around={0.:(0.,0.)},color=black,fill=gray,fill opacity=0.5] (0.,0.) ellipse (1.5 cm and 2.cm);
\draw [rotate around={0.:(0.,0.)},color=black,fill=white] (0.,0.) ellipse (1.cm and 1.3cm);

enter image description here

How can I fill complement of two sets A and B knowing that A is subset of B with venndiagram?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • @Zarko I think, my case is different from your show link. My question is A is a subset of B. – minhthien_2016 Aug 14 '17 at 7:46
  • (i) answers in given link contain a lot of examples which can serve to draw yours (ii) your mwe already show desired result (so far you choose a white fill for subset, but this is easy to change to different color). – Zarko Aug 14 '17 at 11:15
