QCM Poly PASS Probas

Bonjour,

(QCMs d'entraînement du Poly de PASS, Chapitre 4, QCM 3, Item A)

"La loi de probabilité d'une variable aléatoire continue est : p(x<X<x+dx) = f(x) + dx" (voir photo).
Pour une variable continue, la loi de probabilité n'est pas mesurée avec l'intervalle de f(x)dx ?

 

PS : l'item est compté vrai

 

Merci

Salut !

 

La loi de probabilité c'est juste la fonction f(x), c'est un erratum.
