Exercise (1.3)

1. Make correct statements by filling in the symbols $\subset $ or $\not\subset $ in the blank spaces.

i. $\left\{ 2,3,4 \right\}...\left\{ 1,2,3,4,5 \right\}$

Ans:

Given that,

{2,3,4}...(1,2,3,4,5}
To fill in the correct symbols $\subset $ or $\not\subset $ inn the blank spaces

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The element in the set $\left\{ 2,3,4 \right\}$ is also in the set $\left\{ 1,2,3,4,5 \right\}$

$\therefore \left\{ 2,3,4 \right\}\subset \left\{ 1,2,3,4,5 \right\}$

ii. $\left\{ a,b,c \right\}...\left\{ b,c,d \right\}$

Ans:

Given that,

$\left\{ a,b,c \right\}...\left\{ b,c,d \right\}$
To fill in the correct symbols $\subset $ or $\not\subset $ inn the blank spaces

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The element in the set $\left\{ a,b,c \right\}$ is not in the set $\left\{ b,c,d \right\}$

$\therefore \left\{ a,b,c \right\}\not\subset \left\{ b,c,d \right\}$

iii. $\left\{ x:x\text{ is a student of class XI of your school} \right\}...$

$\left\{ x:x\text{ is a student of your school} \right\}$

Ans:

Given that,

$\left\{ x:x\text{ is a student of class XI of your school} \right\}...$

$\left\{ x:x\text{ is a student of your school} \right\}$
To fill in the correct symbols $\subset $ or $\not\subset $ inn the blank spaces

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The set of students of class XI would also be inside the set of students in school

$\backepsilon  \left\{ x:x\text{ is a student of class XI of your school} \right\}\subset $$\left\{ x:x\text{ is a student of your school} \right\}$

iv. $\left\{ x:x\text{ is a circle in the plane } \right\}...$

$\left\{ x:x\text{ is a circle in the same plane with radius 1 unit} \right\}$

Ans:

Given that,

$\left\{ x:x\text{ is a circle in the plane } \right\}...$

$\left\{ x:x\text{ is a circle in the same plane with radius 1 unit} \right\}$
To fill in the correct symbols $\subset $ or $\not\subset $ inn the blank spaces

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The set of circles in the plane with a unit radius will be in the set of the circles in the same plane. So the set of circles in the plane is not in the set of circles with unit radius in the same plane.

$\therefore \left\{ x:x\text{ is a circle in the plane } \right\}\not\subset $$\left\{ x:x\text{ is a circle in the same plane with radius 1 unit} \right\}$

v. $\left\{ x:x\text{ is a triangle in the plane} \right\}...$

$\left\{ x:x\text{ is a rectangle in the plane} \right\}$

Ans:

Given that,

$\left\{ x:x\text{ is a triangle in the plane} \right\}...$

$\left\{ x:x\text{ is a rectangle in the plane} \right\}$

To fill in the correct symbols $\subset $ or $\not\subset $ inn the blank spaces

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

From the given expression itself, we know that the set of triangles in the plane are not in the set of rectangles in the plane.

$\therefore \left\{ x:x\text{ is a triangle in the plane} \right\}\not\subset $$\left\{ x:x\text{ is a rectangle in the plane} \right\}$

vi. $\left\{ x:x\text{ is an equilateral triangle in the plane} \right\}...$

$\left\{ x:x\text{ is a triangle in the plane} \right\}$

Ans:

Given that,

$\left\{ x:x\text{ is an equilateral triangle in the plane} \right\}...$$\left\{ x:x\text{ is a triangle in the plane} \right\}$

To fill in the correct symbols $\subset $ or $\not\subset $ inn the blank spaces

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

From the above expression, we know that the set of equilateral triangles in the plane is in the set of triangles in the same plane

$\therefore \left\{ x:x\text{ is an equilateral triangle in the plane} \right\}\subset $$\left\{ x:x\text{ is a triangle in the plane} \right\}$

vii. $\left\{ x:x\text{ is an even natural number} \right\}...\left\{ x:x\text{ is an integer} \right\}$

Ans:

Given that,

$\left\{ x:x\text{ is an even natural number} \right\}...\left\{ x:x\text{ is an integer} \right\}$
To fill in the correct symbols $\subset $ or $\not\subset $ inn the blank spaces

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The set of even natural numbers are in the set of integers.

$\therefore \left\{ x:x\text{ is an even natural number} \right\}\subset \left\{ x:x\text{ is an integer} \right\}$

2. Examine whether the following statements are true or false

i. $\left\{ a,b \right\}\not\subset \left\{ b,c,a \right\}$

$\left\{ a,b \right\}\not\subset \left\{ b,c,a \right\}$
To examine whether the above statement is true or false

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The element in the set $\left\{ a,b \right\}$ is also in the set $\left\{ b,c,a \right\}$

$\therefore \left\{ a,b \right\}\subset \left\{ b,c,a \right\}$

$\therefore $The given statement is false

ii. $\left\{ a,e \right\}\subset \left\{ x:x\text{ is an vowel in English alpahbet} \right\}$

Ans:

Given that,

$\left\{ a,e \right\}\subset \left\{ x:x\text{ is an vowel in English alpahbet} \right\}$

To examine whether the above statement is true or false

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The element in the set $\left\{ a,e \right\}$ is also in the set $\left\{ a,e,i,o,u \right\}$

$\therefore \left\{ a,e \right\}\subset \left\{ x:x\text{ is an vowel in English alpahbet} \right\}$

$\therefore $The given statement is true.

iii. $\left\{ 1,2,3 \right\}\subset \left\{ 1,3,5 \right\}$

To examine whether the above statement is true or false

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The element in the set $\left\{ 1,2,3 \right\}$ is not in the set $\left\{ 1,3,5 \right\}$ since $2\in \left\{ 1,2,3 \right\}$ and $2\notin \left\{ 1,3,5 \right\}$

$\left\{ 1,2,3 \right\}\not\subset \left\{ 1,3,5 \right\}$

$\therefore $The given statement is false.

iv. $\left\{ a \right\}\subset \left\{ a,b,c \right\}$

Ans:

Given that,

$\left\{ a \right\}\subset \left\{ a,b,c \right\}$

To examine whether the above statement is true or false

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The element in the set $\left\{ a \right\}$ is also in the set $\left\{ a,b,c \right\}$

$\therefore \left\{ a \right\}\subset \left\{ a,b,c \right\}$

$\therefore $The given statement is true.

v. $\left\{ a \right\}\in \left\{ a,b,c \right\}$

Ans:

Given that,

$\left\{ a \right\}\in \left\{ a,b,c \right\}$
To examine whether the above statement is true or false

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

The element in the set $\left\{ a \right\}$ and the elements in the set $\left\{ a,b,c \right\}$ are $a,b,c$

$\therefore \left\{ a \right\}\subset \left\{ a,b,c \right\}$

$\therefore $The given statement is false.

vi. $\left\{ x:x\text{ is an even natural less than 6} \right\}\subset $$\left\{ x:x\text{ is a natural number which divide 36} \right\}$

Ans:

Given that,

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

$\left\{ x:x\text{ is an even natural less than 6} \right\}=\left\{ 2,4 \right\}$

$\left\{ x:x\text{ is a natural number which divide 36} \right\}=\left\{ 1,2,3,4,6,9,12,18,36 \right\}$$\therefore \left\{ x:x\text{ is an even natural less than 6} \right\}\subset $$\left\{ x:x\text{ is a natural number which divide 36} \right\}$

$\therefore $The given statement is true.

3. Let $A=\left\{ 1,2,\left\{ 3,4 \right\},5 \right\}$. Which of the following statements are incorrect and why?

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

From the above statement,

$3\in \left\{ 3,4 \right\}$, however $3\notin A$

$\therefore $The given statement $\left\{ 3,4 \right\}\subset A$ is incorrect

ii. $\left\{ 3,4 \right\}\in A$

Ans:

Given that,

$A=\left\{ 1,2,\left\{ 3,4 \right\},5 \right\}$

To find if $\left\{ 3,4 \right\}\in A$ is correct or incorrect.

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

From the above statement,

$\left\{ 3,4 \right\}\in \left\{ \left\{ 3,4 \right\} \right\}$ so that $\left\{ \left\{ 3,4 \right\} \right\}\in A$

$\therefore \left\{ \left\{ 3,4 \right\} \right\}\subset A$

$\therefore $The given statement $\left\{ \left\{ 3,4 \right\} \right\}\subset A$ is correct.

iv. $1\in A$

Ans:

Given that,

$A=\left\{ 1,2,\left\{ 3,4 \right\},5 \right\}$

To find if $1\in A$ is correct or incorrect.

$\therefore $The statement $1\in A$ is a correct statement.

v. $1\subset A$

Ans:

Given that,

$A=\left\{ 1,2,\left\{ 3,4 \right\},5 \right\}$

To find if $1\subset A$ is correct or incorrect.

A set A is said to be a subset of B if every element of A is also an element of B

$A\subset B$ if $a\in A,a\in B$

From the above statement,

An element of a set can never be a subset of itself. So $1\not\subset A$

$\therefore $The given statement $1\subset A$ is an incorrect statement.

vi. $\left\{ 1,2,5 \right\}\subset A$

Ans:

Given that,

$A=\left\{ 1,2,\left\{ 3,4 \right\},5 \right\}$

From the above statement,

The each element of $\left\{ 1,2,5 \right\}$ is also an element of A, So $\left\{ 1,2,5 \right\}\subset A$

$\therefore $The given statement $\left\{ 1,2,5 \right\}\subset A$ is a correct statement 

vii. $\left\{ 1,2,5 \right\}\in A$

Ans:

Given that,

$A=\left\{ 1,2,\left\{ 3,4 \right\},5 \right\}$

To find if $\left\{ 1,2,5 \right\}\subset A$ is correct or incorrect.

From the above statement,

From the above statement, we notice that,

$3\in \left\{ 1,2,3 \right\}$but $3\notin A$

$\left\{ 1,2,3 \right\}\not\subset A$

$\therefore $The given statement $\left\{ 1,2,3 \right\}\subset A$ is an incorrect statement.

5. How many elements has $P\left( A \right)$, if $A=\varnothing $?

Ans:

Given that,

$A=\varnothing $

To find the number of elements does the $P\left( A \right)$ contain

The collection of all subsets of a set A is called a power set of A and is denoted by $P\left( A \right)$.

We know that if $A$ is a set with $m$elements, that is, $n\left( A \right)=m$, then $n\left[ p\left( A \right) \right]={{2}^{m}}$

If $A=\varnothing $ then $n\left( A \right)=0$

$n\left[ P\left( A \right) \right]={{2}^{0}}$

$=1$

$\therefore P\left( A \right)$ has only one element.

6. Write the following as intervals

i. $\left\{ x:x\in R,-4<x\le 6 \right\}$

Ans:

Given that,

$\left\{ x:x\in R,-4<x\le 6 \right\}$

To write the above expression as intervals

The set of real numbers $\left\{ y:a<y<b \right\}$ is called an open interval and is denoted by $\left( a,b \right)$. The interval which contains the end points also is called close interval and is denoted by$\left[ a,b \right]$

$\therefore \left\{ x:x\in R,-4<x\le 6 \right\}=(-4,6]$

ii. $\left\{ x:x\in R,-12<x<-10 \right\}$

Ans:

Given that,

$\left\{ x:x\in R,-12<x<-10 \right\}$

$\therefore \left\{ x:x\in R,3\le x\le 4 \right\}=\left[ 3,4 \right]$

7. Write the following intervals in set builder form.

i. $\left( -3,0 \right)$

Ans:

Given that,

$\left( -3,0 \right)$

To write the above interval in set builder form

The set of real numbers $\left\{ y:a<y<b \right\}$ is called an open interval and is denoted by $\left( a,b \right)$. The interval which contains the end points also is called close interval and is denoted by$\left[ a,b \right]$

Given that,

$(6,12]$

To write the above interval in set builder form

The set of real numbers $\left\{ y:a<y<b \right\}$ is called an open interval and is denoted by $\left( a,b \right)$. The interval which contains the end points also is called close interval and is denoted by$\left[ a,b \right]$

$\therefore (6,12]=\left\{ x:x\in R,6<x\le 12 \right\}$

ii. $\varnothing $

Ans:

Given that,

$A=\left\{ 1,3,5 \right\},B=\left\{ 2,4,6 \right\},C=\left\{ 0,2,4,6,8 \right\}$

To find if the given set $\varnothing $ is the universal set of A, B and C

It can be observed that,

$A\not\subset \varnothing $

$B\not\subset \varnothing $

$C\not\subset \varnothing $

$\therefore $The set $\varnothing $ cannot be an universal set for A, B and C.

$C\subset $$\left\{ 0,1,2,3,4,5,6,7,8,9,10 \right\}$

$\therefore $The set $\left\{ 0,1,2,3,4,5,6,7,8,9,10 \right\}$ is the universal set of A, B and C

iv. $\left\{ 1,2,3,4,5,6,7,8 \right\}$

Ans:

Given that,

$A=\left\{ 1,3,5 \right\},B=\left\{ 2,4,6 \right\},C=\left\{ 0,2,4,6,8 \right\}$

To find if the given set $\left\{ 0,1,2,3,4,5,6 \right\}$ is the universal set of A, B and C
