Question

Dados los conjuntos:
U (Universal) = {x/x ∈ N; x < 12)
A = {2x -1/x ∈ N; 1 < x < 7)
B = {x-3/x ∈ N; 3 < x < 10)
C = {x+1/x ∈ N; x > 3)

Determina (A-B)' ▲ (B∩C)

PD: el triangulo significa diferencia simetrica

Answer 1

noU={1,2,3,4,5,6,7,8,9,10,11}
A={2,3,4,5,6}
{3,5,7,9,11}
B={4,5,6,7,8,9}
{1,2,3,4,5,6}
C={0,1,2}
{1,2,3}

a) (A-B)'={7,9,11}={1,2,3,4,5,6,8,10}

b) (BnC)={1,2,3}

Respuesta:
{ 4,5,6,8,10}
