Answer 1

Answer:

see the attachment dear ****

Answer 2

A={a,e,i,o,u} and B={a,b,c,d}

(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 sets B should be present in set A

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

Hence B is not a subset of A
