Salut

 

J'ai une question à propos des événements incompatibles.

Dans le cours on a

Or dans le TD de moodle :

Donc deux événements incompatibles ont pour intersection l'ensemble vide et on peut considérer en QCM que c'est égal à 0 ?

Salut, alors tu as entièrement raison: P(AnB) = 0 = ensemble nul signifie bien que ce sont 2 événements incompatibles (c'est la même chose)
