Question

Alguém me ajuda 1. Observe o diagrama e responda:

a) A =
b) B =
c)C =
d) A ∪ B =
e) A ∪ C =
f) B ∪ C=
g) A ∩ B =
h) A ∩ C =
i) B ∩ C =
j) A ∩ B ∩ C =
k) A − B=
l) B− A=
m)A − C =
n) A ∪ B ∪ C =

Answer 1

Resposta:

a) A ={0,1,2,3}

b) B ={2,3,5,6,7}

c)C = {2,4,5}

d) A ∪ B = {0,1,2,3,5,6,7}

e) A ∪ C = {0,1,2,3,4,5}

f) B ∪ C= {2,3,4,5,6,7)

g) A ∩ B ={2,3}

h) A ∩ C ={2}

i) B ∩ C ={2,5}

j) A ∩ B ∩ C = {2}

k) A − B= {0,1}

l) B− A= {5,6,7}

m)A − C = {0,1,3}

n) A ∪ B ∪ C={0,1,2,3,4,5,6,7}
