If A = {2, 4, 6, 8, 10, 12}, B = {3, 4, 5, 6, 7, 8, 10}, find:

Question:

If A = {2, 4, 6, 8, 10, 12}, B = {3, 4, 5, 6, 7, 8, 10}, find:

(i) $(A-B)$

(ii) $(B-A)$

(iii) $(A-B) \cup(B-A)$

 

Solution:

 Given; A = {2, 4, 6, 8, 10, 12}, B = {3, 4, 5, 6, 7, 8, 10}

(i) $(A-B)=\{2,12\}$

(ii) $(B-A)=\{5,7\}$

(iii) $(\mathrm{A}-\mathrm{B}) \cup(\mathrm{B}-\mathrm{A})=\Phi$ or \{\}
