U= {123,4,5,6,7,8,9,10, 11, 12,13,14,15,16}

A= {1,5,10,15}

B={1,2,4,8,10}

C= {1,5,9,11,13,15}

find AUB A-B B-C

\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}

A∪B

=(1,2,3,4,5...17,18)

B′=(1,3,5,7,9...17,19,20,21...)

(A∪B)∩B′=(1,3,5,7,9..17)=A

A′∪A

=UniversalSet

=N

A∪B =(1,2,3,4,5...17,18)

=(1,2,3,4,5...17,18)B′=(1,3,5,7,9...17,19,20,21...)

=(1,2,3,4,5...17,18)B′=(1,3,5,7,9...17,19,20,21...)(A∪B)∩B′=(1,3,5,7,9..17) = A

AA′∪A = UniversalSet

UniversalSet=N
