Answer 2

Let the set be A= {the set of all days in a week}

Sets

Sets are a collection of elements showing similar properties. Sets can be described into two ways-

i) Set builder form- Set builder form gives us the description of the contents of the sets. It gives us the common property of all the elements of the set.

ii) Roster form- Roster form shows us the individual elements of the set in a listed manner.
