Answer 1

A= {0,3,4,5,6,7,8}
B= {2,4,5,6,9}
C= {0,3,6,9,10}
a) A U B= {0,2,3,4,5,6,7,8,9}
b) A ∩ B = {4,5,6}
c) A U C = {0,3,4,5,6,7,8,9,10}
d) A ∩ C = {0,3,6}
e) B ∩ C = {6,9}
f) (A ∩ B) U C = {0,3,4,5,6,9,10}
g) (A ∩ C) U B = {0,2,3,4,5,6,9}
h) (A ∩ B) ∩ C ={6}
i)??
j)??
k) A U (B ∩ C) = {0,3,4,5,6,7,8,9}
l) A ∩ (B ∩ C) = {6}
