Answer 2

Step-by-step explanation:

Answer:

(i) A∪B

We know that

A∪B = {All the elements from set A and all the elements from set B} ={4,5,6,7,8,10,12}

(ii) A∩B

We know that

A∩B = {Elements which are common to both the sets A and B} = {6,8}

(iii) A−B

We know that

A–B = {Elements of set A which are not in set B} = {4,5,7}

(iv) B−A

We know that

B−A = {Elements of set B which are not in set A} ={10,12}
