- [0](https://md.mova.elamur.ai/free/en/corpora/school/lessons/182-pigeonhole-both-colours/0/) — To be sure of a red one and a blue one, imagine the worst luck: all the others come first, and of red and blue only the larger colour.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/lessons/182-pigeonhole-both-colours/1/) — The unlucky hand takes every green one and every one of the larger colour of red and blue, and still lacks the other colour; one more is sure.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/lessons/182-pigeonhole-both-colours/2/) — With 5 red, 8 blue and 4 green: the unlucky hand takes 4 green and 8 blue, that is 12, and the 13th must be red.
- [3](https://md.mova.elamur.ai/free/en/corpora/school/lessons/182-pigeonhole-both-colours/3/) — So 13 are sure.
