Question

Let U={q,r,s,t,u,v,w,x,y,z}, A={q,s,u,w,y}, and B={q,s,y,z}. List the elements in the set A′∪B.


Can you help me understand what it means by

A′∪B

Answer 1

is A' = {r,t,v,x,z} ?

Answer 2

is it
{q,r,s,t,v,x,y,z} ?

Answer 3

A' , i think, in this case would be complement of A in U. It means the elements of U that are not in A

Answer 4

so it would be: A'={r,t,v,x,z}
A′∪B means union of A' and B, so elements that are in bouth A' and B
so it would be :A′∪B ={q,r,s,v,x,y,z}

Answer 5

good enough?

Answer 6

thank you:)
