Question

Calculati:
{0,1,2,3} intersectat {1,2,3,4} intersectat {2,3,4,5} =?
Ajutor!!

Answer 1

{0,1,2,3} intersectat {1,2,3,4}={1,2,3} 
{1,2,3}intersectat {2,3,4,5}={2,3}

Answer 2

{0,1,2,3} intersectat {1,2,3,4} intersectat {2,3,4,5} = {1,2,3} intersectat cu {2,3,4,5}=  {2,3}
Intersectia inseamna numerele care se gasesc si intr-o multime si in alta (elementele comune)
deci raspunsul e {2,3}
