Question

datos os conjuntos A=[0,1,2,3] , B = [0,2,3,5] ,C = 0,2,4,6,8] e D = [5,7,9] , determine ;
a) AUB
b)A-C
c)A-D
d)BUC

Answer 1

A={0,1,2,3} , B = {0,2,3,5} ,C = {0,2,4,6,8} e D = {5,7,9}

a) AUB

AUB = {0,1,2,3,5}

b)A-C

A-C = {1,3}

c)A-D

A-D = {0,1,2,3} = A

d)BUC

BUC = {0,2,3,5,4,6,8}
