Une table de contingence est un outil permettant de résoudre rapidement et facilement des problèmes de probabilités.

Une table de contingence est un tableau qui se présente ainsi :

	A	A*
B	TeX Embedding failed!	TeX Embedding failed!	TeX Embedding failed!
B*	TeX Embedding failed!	TeX Embedding failed!	TeX Embedding failed!
	TeX Embedding failed!	TeX Embedding failed!	1

Une table de contingence comprend donc toutes les probabilités d'évènements, ainsi que celles des intersections possibles entre évènements.

Le principe de calcul est que chaque cellule de fin de ligne ou de fin de colonne est la somme des deux cellules qui précèdent.
Ainsi, pour les lignes :

TeX Embedding failed!

Et pour les colonnes :

TeX Embedding failed!

Pour bien comprendre les relations au sein d'une table de contingence, prenons les illustrations des diagrammes de Venn :

	A	A*
B	TeX Embedding failed!	TeX Embedding failed!	TeX Embedding failed!
B*	TeX Embedding failed!	TeX Embedding failed!	TeX Embedding failed!
	TeX Embedding failed!	TeX Embedding failed!	1
