Let U be the set of cities in the U.S., A be the set of cities with a professional sports team, and B be the set of cities with a symphony

(3) Describe the complement of A

(4) Describe the union of A and B

(5) Describe the intersection of A and B

Respuesta :

Answer:

 A', is the set of all elements in the given universal set U .

But the union of sets is an operation performed on two sets, say A and B, which results in a set that has all elements belonging either to set A and set B or both. The operand of union of set is given by '∪'. You can see, U is also a set which collectively shows all the elements of A, B and of itself.
