Question

A={0,1,2,3,4}
B={2,3,5,6,7}
C={2,4,5,8,9}
Responda:
a=(A∩B) união (B∩C)
b=A ∩ (C união com B)
c=A-B
d= C-A
e=B-C
f=A∩B união C
g=A∩B∩C
h=(A-B) união (C-B)

Answer 1

a- {2,3,5}
b- {2,3,4}
c- {0,1,4}
d- {5,8,9}
e- {3,6,7}
f- {2,3,4,5,8,9}
g- {2}
h- {0,1,4,8,9}

Answer 2

A={0,1,2,3,4}
B={2,3,5,6,7}
C={2,4,5,8,9}
Responda:
a=(A∩B) união (B∩C) = {2,3} U {2,5} ==> {2,3,5}
b=A ∩ (C união com B) = {0,1,2,3,4} ∩ {2,4,5,6,7,8,9}= {2,4}
c=A-B = {0,1,4}
d= C-A = {4,8,9}
e=B-C = {}3,6,7
f=A∩B união C =  {2,3 } U {2,4,5,8,9} = {2,3,4,5,8,9}
g=A∩B∩C = { 2 }
h=(A-B) união (C-B) = { 0,1,4} U { 4,8,9}==> { 0,1,4,8,9 }
