Question

Sendo A= {1,2,3,4,5,6} B= {4,5,6,7} C= {6,7,8,9,10}, determine
a) AuB
b) AuC
c) BuC
d) AuBuC
e) A∩B
f) A∩C
g) B∩C
h) A∩B∩C

Answer 1

a)A∪B = {1,2,3,4,5,6,7}
b)A∪C = {1,2,3,4,5,6,7,8,9,10}
c)B∪C = {4,5,6,7,8,9,10}
d)A∪B∪C = {1,2,3,4,5,6,7,8,9,10}
e)A∩B = {4,5,6}
f)A∩C = {6}
g)B∩C = {6,7}
h)A∩B∩C = {6}

Answer 2

a) AuB= {1, 2, 3, 4, 5, 6, 7}

b) AuC= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

c) BuC= {4, 5, 6, 7, 8, 9, 10}

d) AuBuC= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

e) AΠB= {4, 5, 6}

f) AΠC= {6}

g) BΠC= {6, 7}

h) AΠBΠC= {6}

Espero ter ajudado ^^
