Question

Answer 1

Answer:

(1,2,3,4,5,6,7)

Step-by-step explanation:

is the answer

Answer 2

A = { 1, 2, 3, 4 }

B = { 5, 6, 7 }

As no element is common in both the sets.

So, A ∩ B = Ф

But if we take ( A ∪ B ) we get { 1, 2, 3, 4, 5, 6, 7 } as the elements of both the sets get combined to form union.
