Question

List out some sets A and B and choose their elements such that A and B

Answer 1

Step-by-step explanation:

Two sets A and B are said to be disjoint,

if ,they have no element in common.

Thus, A = {1, 2, 3} and B = {5, 7, 9} are disjoint sets

; but the sets C = {3, 5, 7} and D = {7, 9, 11} are not disjoint;

for, 7 is the common element of A and

Answer 2

Step-by-step explanation:

Two sets A and B are said to be disjoint, if they have no element in common. Thus, A = {1, 2, 3} and B = {5, 7, 9} are disjoint sets; but the sets C = {3, 5, 7} and D = {7, 9, 11} are not disjoint; for, 7 is the common element of A and
