Consider set A as

A = {1, 2, 3, 4, 5}


Empty set is the subset of all sets

Subset is a set which contains all elements of the other set

Since empty set has no elements,

it will be the subset of every set

∴ ϕ ⊂ A


Set is the subset of itself

Since, all elements of A are in A,


A is a subset of A

∴ A ⊂ A
