(a) No circles are polygons
(b) Some quadratic equations have equal roots
Advertisements
उत्तर
(a) Let u: The set of closed geometrical figures in the plane.
Let A: The set of all polygons and
B: The set of all circles
Hence the following is the Venn diagram.
(b) Let u: The set of all equations.
Let A: The set of all quadratic equations and
B: The set of all quadratic, equations having equal roots.
Hence the following is the Venn d6agram.

Draw a Venn diagram for the truth of the following statement :
All rational number are real numbers.
If A and B are two set such that \[A \subset B\]then find:
\[A \cap B\]
If A and B are two sets such that \[A \subset B\] then find:
\[A \cup B\]
If A = {1, 2, 3, 4, 5}, B = {4, 5, 6, 7, 8}, C = {7, 8, 9, 10, 11} and D = {10, 11, 12, 13, 14}, find:
\[A \cup C\]

Express the truth of the following statements with the help of Venn diagram:
(a) No circles are polygon
(b) If a quadrilateral is rhombus , then it is a parallelogram .
From the given diagram find :
A' ∩ B
Two sets A and B are such that A ∩ B = Φ. Draw a venn-diagram to show the relationship between A and B. Shade the region representing :
A ∪ B
In the given diagram, shade the region which represents the set given underneath the diagrams: (P ∩ Q)'
From the given diagram, find :
(i) (A ∪ B) - C
(ii) B - (A ∩ C)
(iii) (B ∩ C) ∪ A
Verify :
A - (B ∩ C) = (A - B) ∪ (A - C)
