Answer:

1)  A - B = {2 , 4 , 8 , 10}

2) B - A =  {3 , 9 , 12 , 15}

3) A ∩ B = {6}

4) A ∪ B = {2 , 3 , 4 , 6 , 8 , 9 , 10 , 12 , 15}

Step-by-step explanation:

Given,

A = {2 , 4 , 6 , 8 , 10}

B = {3 , 6 , 9 , 12 , 15}

To Find :-

1. A - B

2. B - A

3. A ∩ B

4. A ∪ B

Solution :-

1) A - B

= {2 , 4 , 6 , 8 , 10 } - {3 , 6 , 9 , 12 , 15}

= {2 , 4 , 8 , 10}

∴ A - B = {2 , 4 , 8 , 10}

2) B - A

= {3 , 6 , 9 , 12 , 15} - {2 , 4 , 6 , 8 , 10}

= {3 , 9 , 12 , 15}

∴ B - A =  {3 , 9 , 12 , 15}

3) A ∩ B

= {2 , 4 , 6 , 8 , 10} ∩ {3 , 6 , 9 , 12 , 15}

= {6}

∴ A ∩ B = {6}

4) A ∪ B

= {2 , 4 , 6 , 8 , 10} ∪ {3 , 6 , 9 , 12 , 15}

= {2 , 3 , 4 , 6 , 8 , 9 , 10 , 12 , 15}

∴ A ∪ B = {2 , 3 , 4 , 6 , 8 , 9 , 10 , 12 , 15}
