BUNA !AM NEVOIE DE AJUTOR LA URMATOAREA PROBLEMA!​

Answer 1

numere prime

2, 3, 5, 7, 11, 13

avem 6 numere prime

p = 6×100/15 = 600/15 = 40%

cazul 1

p + p + p = 52

intre cele 15 cartonase avem 7 cartonase cu numere pare

2, 4, 6, .. 12, 14

mai adaugam 3

total cartonase = 18

total cartonase pare = 10

p = 10×100/18 = 1000/18 = 55,(5) %

cazul 2

i + i + p = 52

adaugam un cartonas par = 8

total cartonase = 18

total cartonase pare = 8

p = 8×100/18 = 800/18 = 44,(4) %
