Question

How can you say that a set is a subset of another set. Give example in real life situation.

Answer 1

Example: the set {1, 2, 3, 4, 5}

A subset of this is {1, 2, 3}. Another subset is {3, 4} or even another is {1}, etc. But {1, 6} is not a subset, since it has an element (6) which is not in the parent set.

Answer 2

The set { 1,2,3,4,5 }.................
