Question 1

1 / -0

Which class-interval has the maximum frequency?

$0-10$

$30-40$

$10-20$

$40-50$

Solution

We will form table from above histogram:

$CI$	$Frequency$
$0-10$	$15$
$10-20$	$10$
$20-30$	$20$
$30-40$	$25$
$40-50$	$10$
$50-60$	$5$

\Rightarrow

From above table table we can see,

30-40

has frequency

25

which is maximum.

\therefore

The class-interval has the maximum frequency is

30-40

Question 2
1 / -0

What is frequency of the class- interval $20-30$ ?

A
$25$

B
$20$

C
$5$

D
$10$

Solution

$\Rightarrow$ In the above histogram we can see that, frequency of the class interval $20-30$ is $20$
Question 3
1 / -0

When a die is thrown, list the outcomes of an event of getting:
not a prime.

A
$2,3,5$

B
$1, 4, 6$

C
$1,2,5$

D
$1,3, 6$
Question 4
1 / -0

When a die is thrown, list the outcomes of an event of getting:
A number greater than $5$

A
$5$

B
$4$

C
$6$

D
$3$

Solution

For a die, the possible outcomes are, $1,2,3,4,5,6$
From the above outcomes, only $6$ is greater than $5$
So, the possible outcome is $6$ .
Question 5
1 / -0

The probability of an event that cannot happen is ____?

A
$0$

B
$1$

C
$2$

D
$3$

Solution

We know that. all probabilities are between $0$ and $1$ inclusive.
A probability of $0$ means an event is impossible, it cannot happen.
A probability of $1$ means an event is certain to happen, it must happen.
Thus the probability of an event that cannot happen is $0$ .
Question 6
1 / -0

The probability of an event that is certain to happen is ____?

A
$1$

B
$2$

C
$3$

D
$4$

Solution

The event that is sure to happen is called a certain event and probability of such an event is $1$ as this event is bound to happen.
Question 7
1 / -0

The probability of an impossible event is ____

A
$3$

B
$2$

C
$1$

D
$0$

Solution

Probability of event in $E$ , $P\left( E \right) =\dfrac { \text {number of events in E} }{ \text {Total number of possible events}}$
If the desirable event does not happen even once, then the numerator in the above formula becomes equal to zero.
Question 8
1 / -0

When a die is thrown, list the outcomes of an event of getting:
a number lesser than $5$ .

A
$1, 2, 3, 4$

B
$1, 2, 3$

C
$3, 4, 5$

D
$4, 5$
Question 9
1 / -0

How many class-intervals have equal frequency ?

A
$2$

B
$1$

C
$3$

D
None

Solution

$\Rightarrow$ In above histogram we can see, class intervals $10-20$ and $40-50$ have same frequency which is $10$ .
$\therefore$ The class intervals have equal frequency are $2$ .
Question 10
1 / -0
