- [0](https://md.mova.elamur.ai/free/en/corpora/school/lessons/175-venn-neither/0/) — Draw two overlapping circles.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/lessons/175-venn-neither/1/) — The children who like both things stand in the middle part, where the circles meet.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/lessons/175-venn-neither/2/) — If we add the two groups, the children in the middle are counted twice, so we take them away once.
- [3](https://md.mova.elamur.ai/free/en/corpora/school/lessons/175-venn-neither/3/) — 30 children: 14 like football, 12 like chess, 5 like both.
- [4](https://md.mova.elamur.ai/free/en/corpora/school/lessons/175-venn-neither/4/) — At least one: 14 + 12 - 5 = 21, neither: 30 - 21 = 9.
