Answer 1

Given  : A is an empty set and B is a set of vowels,

To find : A∩B is

A

B

A or B

None of these

Solution:

A is an empty set

=> A = { }  or  Ф

B is a set of vowels,

=> B = { A , E , I , O , U }

A∩B    is common elements in A & B

=> A∩B    = { }  or  Ф

A = { }  or  Ф

=>  A∩B    = A

A∩B  is  A  if  A is an empty set and B is a set of vowels

Answer 2

Answer:

Null set

Step-by-step explanation:

We are given that A is an empty set or a null set. A null set has no elements in it.

Secondly regarding set B, the elements in B would be

B = {A, E, I , O , U}

Now A∩B means that we need to find the common elements between set A and B. SInce in our case A is already empty, so an empty cannot have anything in common with some other set. Hence result of

A∩B is a null set
