Answer 1

1.

a) AuB = {0, 2, 4, 6, 8, 10} u {0, 3, 6, 9} = {0,2,3,4,5,8,9,10}

AnB = {0,6}
A\B = {2,4,8,10}
b) AuB = {1,2,4,6} u {2,3,4,5,6,7} = {1,2,3,4,5,6,7}
AnB = {2,4,6}
A\B = {1}

c) AuB = {1,3,5} u {0,2,3,4,5} = {0,1,2,3,4,5}
AnB = {3,5}
A\B = {1}
d)AuB = {0,2,3,5,7,9} u {1,3,4,6,8} = {0,1,2,3,4,5,6,7,8,9}
AnB = {3}
A\B = {0,2,5,7,9}

 

2. A = {1,2,3,7,8,9} B = {1,2,3,4,5,6} C={5,6,7,8,9}
a) (AuB)nC = {1,2,3,4,5,6,7,8,9} n {5,6,7,8,9} = {5,6,7,8,9}

b) (AnB)uC = {1,2,3} u {5,6,7,8,9} = {1,2,3,5,6,7,8,9}

c) Au(BnC) = {1,2,3,7,8,9} u {5,6} = {1,2,3,5,6,7,8,9}
d) (AnB)\C = {1,2,3} \ {5,6,7,8,9} = {1,2,3}
