vi) 6 ___________A​

Answer 1

Step-by-step explanation:

i) 1 and 3 are elements of A and a set consisting of 1 and 3 will be a proper subset of A

ii) Since 1 is an element of A so 1 belongs to A

iii) Since {1} is an element of A so 1 belongs to A

iv) 1, 2 and 3 are elements of A and a set consisting of 1, 2 and 3 will be a proper subset of A

v) 4 and 5 are elements of A and a set consisting of 4 and 5 will be a proper subset of A.

vi) 6 is not an element of A so 6 does not belong to A
