Question

1 point If A and B are sets and A ∪ B = A ∩ B then which of the following is(are) true? Either one of A or B is empty set B is proper subset of A . A = B A is proper subset of B .

Answer 1

Answer:

Set B is proper subset of Set A

Step-by-step explanation:

1. A and B are two sets

2. A U B means complete A and complete B

3. A ^ B means only intersection that is in between A and B

4. Among the provided sets, Either one of A or B is empty is false because it is not A - B or B - A

5. A = B where A is proper subset of B is false because A = B != A ^ B

6. Answer is Set B is proper subset of Set A
