Answer:
(a) Set A = {1,2,3}
Set B = {1,2,4,5}
(b) Set A Ç B = {1,2}
Set A e B = {1,2}
Step-by-step explanation:
As per the question,
Given data :
A ∪ B = read as A union B = {1,2,3,4,5}
A ∩ B = read as A intersection B = {1,2}
(a) An example of sets A and B such that A ∩ B = {1,2} and A U B = {1,2,3,4,5).
So, first draw the Venn-diagram, From below Venn diagram, One of the possibility for set A and set B is:
Set A = {1,2,3}
Set B = {1,2,4,5}
(b) An example of sets A and B such that A Ç B and A e B,
Set A Ç B read as common elements of set A in Set B.
Therefore,
Set A Ç B = {1,2}
Set A e B implies that which element/elements of A is/are present in set B.
Therefore,
Set A e B = {1,2}
