- 3. if R contains itself, then R must be a set that is not a member of itself by the definition of R, which is contradictory
- 5. is relation obtained by interchanging or swapping the elements or coordinates of each ordered pair in the relation
- 6. the set of all subsets of the Set A including the Set itself and the null or empty set
- 7. is a collection of objects (called elements) in which elements may occur more than once.
- 8. the lists of all the elements that are in set A but that are not present in set B
- 9. occurs when you switch the hypothesis and the conclusion in a statement, and negate both statements
- 12. the set of all the elements which lie in set A and set B or both the elements in A and B altogether. T
- 14. the set that includes all the elements of the universal set that are not present in the given set
- 15. provides an organized method/formula to find the number of elements in the union of a given group of sets, the size of each set, and the size of all possible intersections among the sets.
- 16. the number of elements in a mathematical set.

- 1. is the result of reversing its two constituent statements
- 2. is the set that includes all those elements that are common to both A and B.
- 4. is a collection of objects or groups of objects.
- 10. is a compound statement in Maths which always results in Truth value
- 11. A set A is a subset of another set B if all elements of the set A are elements of the set B
- 13. a counting technique which generalizes the familiar method of obtaining the number of elements in the union of two finite sets
