Question

determinati multimile A si B stiid ca AuB=[1,2,3,4,5,6],A^B=[2,3] si A\B=[1,5]

Answer 1

din A int B={2,3}⇒2,3 se gasesc atat in A cat si in B
A\B={1,5}⇒1,5 se gasesc in A dar nu si in B

A={1,2,3,5}
B={2,3,4,6}

Answer 2

AuB=[1,2,3,4,5,6], toate elementele ambelor multimi
A^B=[2,3]  = elementele comune ambelor multimi
 si A\B=[1,5]  ce are A si nu are B
A={1.2.3.5}        si B={2,3,4,6}
