Bonjour,

a)

total = 11 + 39 = 50

femmes = 11/50 = 0,22 = 22/100 = 22%

hommes = 39/50 = 0,78 = 78/100 = 78%

femmes = 960000x22/100 = 211200

hommes = 960000x78/100 = 748800

b) total = 12 + 9 + 4 = 25

province = 12/25 = 0,48 = 48/100 = 48%

IDF = 9/25 = 0,36 = 36/100 = 36%

étranger = 4/25 = 0,16 = 16/100 = 16%

province = 960000x48/100 = 460800

IDF =  960000x36/100 = 345600

étranger = 960000x16/100 = 153600
