Question

Let A={a,e,i,o,u} & B={a,b,c,d} . is A is a subset of B ? No.(why?) . Is B is a subset of A?No. (why?)​

Answer 1

A={a,e,i,o,u}

B={a,b,c,d}

Step-by-step explanation:

(I) For a set to be a subset of another set it needs to have all elements present in the another set.

In set A{e,i,o,u} elements are present but

these are not present in set B.

hence A is not a subset of B

(II) For this condition to be true, are elements of set B should be present in set A.

In set B{b,c,d} elements are present but there elements are not present in set A.

hence B is not a subset of A.

Answer 2

Is A is a subset of B ? No

For a set to be sub set of another set, it needs to have all elements present in the another set

In set A elements are present but these are not present in set B

Is B is a subset of A?No

For this condition to be true, are elements of sets B should be present in set A

In set B elements are present but these are not present in set A
