Question 1
1 / -0

If $$P(A) = 0$$, then the event $$A$$

A
Will never happen

B
Will always happen

C
May happen

D
May not happen

Solution

The probability is the possibility of happening of an event.
If the probability of an event is zero, it means the event is an impossible event and it will never occur.
Question 2

A survey was made to find the type of music that a certain group of young people linked in a city. Above pie chart shows the findings of this survey.
From this pie chart answer which type of music is liked by the maximum number of people?

A
$$\text{Semi Classical}$$

B
$$\text{Classical}$$

C
$$\text{Light}$$

D
$$\text{Folk}$$

Solution

Choose the correct answer from the alternatives given.
The family actually paid Rs. $$4672$$ on grocery. What is the difference in the amount budgeted and spent on grocery?

A
Rs. $$1738$$

B
Rs. $$1672$$

C
Rs.$$1728$$

D
Rs. $$1038$$

Solution

Amount budgeted on grocery $$= 20\%\ of\ 32,000 =$$ Rs. $$6,400$$
So, required difference $$= 6,400 - 4,672 =$$ Rs. $$1,728$$
Question 4
1 / -0

Data represented using circle is known as

A
Bar Graph

B
Histogram

C
Pictograph

D
Pie chart

Solution

A pie chart represents the data in circular form.
Hence, option $$D$$ is correct.
Question 5
1 / -0

Observe the adjoining bar graph, showing the number of one-day international matches played by cricket teams of different countries. Choose the correct answer from the given four options:
How many matches did South Africa play?

A
$$16$$

B
$$18$$

C
$$20$$

D
$$24$$

Solution

The given bar graph represents the number of matches played by cricket teams of different country.
We can prepare frequency table from given bar graph as follows:
Country No. of matches
India $$30$$
Pakistan $$24$$
West Indies $$20$$
England $$28$$
South Africa $$18$$
Australia $$32$$
Sri Lanka $$24$$
Clearly, the number of matches played by South Africa is $$18$$.
Hence, option $$B$$ is correct.
Question 6
1 / -0

Observe the following pictograph which shows the number of ice cream cones sold by school canteen during a week. Chose the correct answer from the given options:
The maximum number of ice cream cones were sold on:

A
Tuesday

B
Friday

C
Wednesday

D
Thursday

Solution

After observing the pictograph, we can say that

Monday = 2 x 5 = 10 ice creams
Tuesday = 2 x 8 = 16 ice creams
Wednesday = 2 x 6 = 12 ice creams
Thursday = 2 x 3 + 1 = 7 ice creams
Friday = 2 x 7 = 14 ice creams
Saturday = 2 x 4 = 8 ice creams

Hence, the maximum number of ice cream were sold on Tuesday i.e. 16 ice cream.
So, Option ( A ) is the correct answer.
Question 7
1 / -0

Observe the following pictograph which shows the number of ice cream cones sold by school canteen during a week. Chose the correct answer from the given options:
The minimum number of ice cream cones were sold on:

A
Monday

B
Saturday

C
Tuesday

D
Thursday

Solution

After observing the pictograph, we can say that

Monday $$= 2\times 5 = 10$$ ice creams
Tuesday $$= 2\times 8 = 16$$ ice creams
Wednesday $$= 2\times 6 = 12$$ ice creams
Thursday $$= 2\times 3 + 1 = 7$$ ice creams
Friday $$= 2\times 7 = 14$$ ice creams
Saturday $$= 2\times 4 = 8$$ ice creams

Hence, the minimum number of ice cream were sold on Thursday i.e. $$7$$ ice cream.
So, Option ( D ) is the correct answer.
Question 8
1 / -0

Fill in the blank:
The height of a rectangle in a histogram represent _______.

A
class interval

B
midpoint

C
frequency density

D
frequency

Solution

We know, histogram is a graphical representation of data using bars of equal width and no gaps between them. The height of the bars gives the frequency of the particular class interval.

Therefore, the height of a rectangle in a histogram represents the frequency.

Hence, option $$D$$ is correct.

...view full instructions

Find the central angle of pie chart for winter.

A
$$90$$

B
$$120$$

C
$$150$$

D
None of these

Solution

Central Angle for Summer $$= \dfrac { 90 }{ 360 } \times 360 = 90$$ degree

Central Angle for Rainy $$= \dfrac { 120 }{ 360 } \times 360 = 120$$ degree

Central Angle for Winter $$= \dfrac { 150 }{ 360 } \times 360 = 150$$ degree
Question 10
1 / -0

What is the sum of the frequencies of the intervals 40-50 and 50-60 ?

A
$$15$$

B
$$25$$

C
$$45$$

D
$$20$$

Solution

$$\Rightarrow$$ In above graph we can see, frequencies of the intervals $$40-50$$ and $$50-60$$ are $$10$$ and $$5$$.
$$\therefore$$ The sum of the frequencies of the intervals $$40-50$$ and $$50-60$$ $$=10+5=15$$
