Examples of null sets are:
The set of dogs with six legs.
The set of squares with 5 sides.
The set of cars with 20 doors.
The set of integers which are both even and odd.
1 5 1
You're welcome :)
yeah this is right because none of this is true which leave the set empty or = { }.. but maybe a dog can have 6 legs..^_^
An empty set is basically a set with no kinds of elemnts in it. If Set A has 3 things and Set B has none, Set B is an empty set.
