Dado o conjunto A = {3, 4, 5, 6, 7, 8, 9, 10}, B = {9, 10, 11, 12} e C = {5, 7, 9, 11, 13}, determine:
a. A∩B
b. AUC
c. BUC
d. AUB
e. A–B
f. B–C
g. A∩C
h. C–B
i. B∩C

Answer 1

Resposta:

a. A∩B=  { 9, 10}

b. AUC= { 3, 4, 5, 6, 7, 8, 9, 10 11, 13}

c. BUC= {5, 7, 9, 10, 11, 12, 13}  

d. AUB= { 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

e. A–B= { 3, 4, 5, 6, 7, 8}

f. B–C= {10, 12}

g. A∩C= { 5, 7, 9}

h. C–B= {5, 7, 13}

i. B∩C= {9, 11}
