Question

If A = {1, 2, 3, 4, 5}; B = {4, 5, 6, 7}, then find A - B and B - A, Are they equal ?​

Answer 1

Question :-

If A = {1, 2, 3, 4, 5}; B = {4, 5, 6, 7}, then find A - B and B - A, Are they equal ?

Solution :-

Given sets are

• A = {1, 2, 3, 4, 5}
• B = {4, 5, 6, 7}

A - B = {1, 2, 3, 4, 5} - {4, 5, 6, 7}

= {1, 2, 3}

B - A = {4, 5, 6, 7} - {1, 2, 3, 4, 5}

= {6, 7}

No, A - B ≠ B - A

Answer 2

Answer:

A-B ≠ B-A

Step-by-step explanation:

A = {1, 2, 3, 4, 5}; B = {4, 5, 6, 7},

A-B = [1,2,3)

B-A = [6,7]

So A-B ≠ B-A
