Answer 1

a) A uni B= {0,2,3,4,5,6,7,8,9}

b) A inter B= {4,5,6}

c) A uni C= {0,3,4,5,6,7,8,9,10}

d) A inter C= {0,3,6}

e) A inter C={0,3,6}

f) (A inter B) uni C={0,3,4,5,6,9,10}

g) ( A inter C) uni B={0,2,3,4,5,6,9}

h)(A inter B) Inter C={6}

i) (A uni B) inter C={0,3,6,9}

j) ( A uni C) inter B={4,5,6,9}
