3. What is the use of Venn Diagramme?------------------------------> They are useful for illustrating the relationships between elements in a set.


4. What is a sub set?------------------------------------------------------------------> If all the elements of set A are present in set B and set B has few additional elements as well then ?


5. What is a proper subset?----------------------------------------------------------> If every element of set A is an element of set B but at least one element of set B is not an element of set A then?


6. If {1, 2} is subset of {3, 2, 1} then {1, 2} is also ---------- of {3, 2, 1}

11. Pick the correct choice where set A and set B are disjoint sets?




Math Class 9
12. What does the following Venn Diagramme indicates?


13. What are overlapping sets? ---------------------------> Sets which have few common elements ie In Set A = { 1, 3, 4 } and set B = { 3, 4, 5, 6 } 3 and 4 are common.


14. Pick the correct choice where set A and set B are overlapping sets?




Math Class 9
15. What does the following Venn Diagramme indicates?


16. What are Equal sets? ------------------------------> The sets have the same elements ie Set A = { 1, 3, 4 } and set B = { 1,3, 4 }.


17. Pick the correct choice where set A and set B are equal sets?

19. What is a Universal set ?------------------------------------------------> A set which has all the elements of all the sets under consideration is called a universal set


20. If A is a set of students of class 10, B is a set of students of class 9, C is a set of students of class 8 then set consisting of all students of the school would be


21. What does the following Venn Diagramme indicates?



22. If U is a universal set and set A is a subset of set U then U - A (U minus A) would be?


23. What does the green area in the diagramme indicates?


24. What is a power set? ------------------------------------------------------------------------> If A is any set then a set consisting of all the subsets of set A is call ed power set of set A.


25. How power set of set A will be indicated?


26. If A + {1,2} then power set of set A will be?


27. Set A and B are equal if A = {1, 2, 3} and B = {3, 2, 1, 1},


28. Why set A and B are equal if A = {1, 2, 3} and B = {3, 2, 1, 1},

32. How the union of sets A = {1, 3, 5 } and set B = { 1, 3, 7, 9 } will be indicated through Venn Diagramme


33. What is meant by the word "Intersection"?





Math Class 9
34. How intersection is carried out in sets?



35. What will be correct intersection of A = {1, 3, 5 }, B = { 1, 3, 7, 9 }



36. What will be correct Union and Intersection of A = {1, 3, 5 }, B = { 1, 3, 7, 9 }


37. How the Intersection of sets A = {1, 3, 5 } and set B = { 1, 3, 7, 9 } will be indicated through Venn Diagramme.
