Question

(b) A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
B = {1, 3, 5, 7, 9, 11, 13}
C = {2, 4, 6, 8, 10, 12, 14}
D = {2,3,5, 7, 11, 13, 17}
Then find
(i) AUC
(ii) Bnc
(iii) A-D
(iv) (A-B) U (B - A)​

Answer 1

A U C = {1,2,3,4,5,6,7,8,9,10,12,14}

B n C = { }

A-D ={1,4,,6,8,9,10}

A-B U B-A

=> {2,4,6,8,10} U {11,13}

=> {2,4,6,8,10,11,13}
