State true  or false and your reason for choosing that and an example for each.
Set notation.
A' U B' is equal to (A U B)'
A'∩ B' is equal to (A ∩ B)'

Answer :

let the universal set be u={1,2,3,4,5,6,7,8,9
a={1,2,5}
b=[4,5,8}

A'=u-a
   ={3,4,6,7,8,9}

B'=u-b
   ={1,2,3,6,7,9}

A'UB'={1,2,3,4,5,6,7,8,9}
so it is false

A' intersectionB'= { }

so it is false
