Ancien Responsable Matière Noel_Flantier Posted December 31, 2019 Ancien Responsable Matière Share Posted December 31, 2019 Bonjour, Concernant l'item B de ce qcm, je ne comprends pas pourquoi dans la correction il a fallu diviser par 10 sachant que l'on cherche le nombre moyen de rechutes ? https://www.noelshack.com/2019-01-2-1577814890-2019-12-31-6.png Un grand merci d'avance !!

Solution Chat_du_Cheshire Posted December 31, 2019 Solution Share Posted December 31, 2019 (edited) c'est une erreur, la bonne réponse est : 0*0,35 + 1*0,25 + 2*0,2 + 3*0,1 + 4*0,1 = 1,35 (si je me trompe pas) Edited December 31, 2019 by Chat_du_Cheshire Quote Link to comment Share on other sites More sharing options...
