Examine whether t

Answer :

(i) Let us assume that A = {a, b} and B = {b, c, a}


Now, we can observe that every element of A is an element of B.


Thus, A B


The statement is false.


(ii) Let us assume that A = {a, e} and


B = {x: x is a vowel in the English alphabets}


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


Now, we can observe that every element of A is an element of B.


Thus, A B


The statement is true.


(iii) Let us assume that A = {1, 2, 3} and B = {1, 3, 5},


Now, we can observe that 2 belongs to A but 2 does not belongs to B.


Thus, A B


The statement is false.


(iv) Let us assume that A = {a} and B = {b, c, a}


Now, we can observe that every element of A is an element of B.


Thus, A B


The statement is true.


(v) Let us assume that A = {a} and B = {b, c, a}


Now, we can observe that every element of A is an element of B.


Thus, A B


The statement is false.


(vi) Let us assume that A = {x:x is an even natural number less than 6}


= {2, 4}


and B = {x:x is a natural number which divide 36}


= {1, 2, 3, 4, 6, 9, 12, 18, 36}


Now, we can observe that every element of A is an element of B.


Thus, A B


The statement is true.
