Question

1. Given A = {2,4,5,7) and B= {1,2,3,4,6} Represent the following through Venn diagram i) AUB ii) AB iii) A-B iv) B-A​

Answer 1

Step-by-step explanation:

1 :- AUB = {1,2,3,4,5,6,7}

2:- A*B = {(2,1),(2,2),(2,3),(2,4),(2,6),(4,1),(4,2),(4,3),(4,4),(4,6),(5,1),(5,2),(5,3),(5,4),(5,6),(7,1),(7,2),(7,3),(7,4),(7,6)}

3:- A-B = means elements of A which are not the elements of B.

then A-B = { 5,7}

4:- B-A = means elements of B which are not the elements of A.

then B-A = {1,3,6}
