Sets

Question 1

What are sets?

Answer 1

A set is a well defined collection of objects or elements.

Question 2

What is the union of sets?

Answer 2

The union of two or more sets is the group of all the elements formed by combining the given sets.

(It’s a subset from the main set)

Question 3

What is the intersection of sets?

Answer 3

The intersection of two or more sets is the group of all elements that are common to the sets given.

(It is a subset from the main set)

Question 4

What are disjoint sets?

Answer 4

Disjoint sets have no elements in common. No intersection is present. The intersection would be an empty set.

Question 5

What is the complement of a set?

Answer 5

The complement of a set is the set of elements in the universal set not present in the given set.

Question 6

What is the difference of sets?

Answer 6

The difference of a set is to subtract one set from the other. Which would list all the elements in the minuend excluding the intersection.

A (elements) minuend - B (elements) subtrahend = A (elements)
