Answer:
Set B is not a subset of A.
Step-by-step explanation:
If there are sets, A and B with some elements, then B can be called subset of A, if every element of B is present in set A.
Example.
Example
A is set of integers
B is set of natural numbers
we know set of integers is all the negative numbers, 0 and all the positive discrete numbers like
A = {......-3,-2,-1,0,1,2,3,4........}
B is set of positive discrete numbers from 1 to infinity)
B = {1,2,3,4........}
Thus, we see every element of B is present in A . Hence B is subset of A
___________________________________________
Given
A = {2, 3, 5, 7, 11}
B = {3, 5, 7, 9, 11)
Here,
In set B . elements 3,5,7,11 are present in set A, but
Element 9 from set B is missing Set A.
Since, every element of Set B is not present in set A hence
Set B is not a subset of A.
