bonjour
1 ) proba que la valeur soit de 20 points = 60 /300 = 0.2
2 ) soit < 25 points = 220/300 = 0.733.....
3 ) soit au moins de 50 points = 30/300 = 0.1
4 ) entre 5 et 10 points , P = 160/300 = 0.53....
> 10 points , P = 140/300 = 0.4666......
bonjour,
total des jetons:
90+70+ ..... =300
1)
60/300 = 6/30 = 1/5
2)
60+70+90 =>
220/300 = 22/30 = 11/15
3)
90+70+60+50+20 =290
=> 290/300 = 29/30
4)
90+70 = 160
300 -160 = 140
140< 160
donc oui!
