**Ex 5.3 Class 8 Maths Question 1.**

List the outcomes you can see in these experiments.(a) Spinning a wheel

(b) Tossing two coins together

**Solution:
**(a) On spinning the wheel, we can get the following
outcomes: {A, B, C, D}

(b) When two coins are tossed together, we get the following outcomes:

{HH, HT, TH, TT}

(Where H denotes Head and T denotes Tail)

**Ex 5.3 Class 8 Maths Question 2.**

When a
die is thrown, list the outcomes of an event of getting(i) (a) a prime number (b) not a prime number

(ii) (a) a number greater than 5 (b) a number not greater than 5

**Solution:****
**(i) (a)
When a die is thrown, the sample space = {1, 2, 3, 4, 5, 6}

The
prime numbers are 2, 3 and 5.

Required outcomes = {2, 3, 5}

(b) Outcomes for not a prime number are 1, 4 and
6.

Required outcomes = {1, 4, 6}

(ii) (a) When a die is thrown, the sample space
= {1, 2, 3, 4, 5, 6}

Outcomes
for a number greater than 5 = 6

Required outcome = {6}

(b) Outcomes for a number not greater than 5 are
1, 2, 3, 4, 5.

Required outcomes = {1, 2, 3, 4, 5}

**Ex 5.3 Class 8 Maths Question 3.**

Find
the(a) Probability of the pointer stopping on D in (Question 1-(a))?

(b) Probability of getting an ace from a well-shuffled deck of 52 playing cards?

(c) Probability of getting a red apple, (see figure below)

**(a) Refer to figure in Question 1-(a)**

Total number of sectors = 5

Number of sector where the pointer stops = 1, i.e., D

Probability of pointer stopping at D = 1/5

(b) Number of aces = 4 (one from each suit, i.e., heart, diamond, club and spade)

Total number of playing cards = 52

Probability of getting an ace (iii) Total number of apples = 7

Number of red apples = 4

Probability of getting red apples

**Ex 5.3 Class 8
Maths Question 4.**

Numbers 1 to 10 are written on ten separate slips
(one number on one slip), kept in a box and mixed well. One slip is chosen from
the box without looking into it. What is the probability of:(i) getting a number 6?

(ii) getting a number less than 6?

(iii) getting a number greater than 6?

(iv) getting a 1-digit number?

**Solution:
**(i) Probability of getting a number 6 = 1/10

(ii) Probability of getting a number less than 6 = 5/10 = ½

[∵ Numbers less than 6
are 1, 2, 3, 4, 5]

(iii) Probability of getting a number greater than 6 = 4/10 = 2/5

[∵ Numbers greater
than 6 are 7, 8, 9, 10]

(iv) Probability of getting a 1-digit number = 9/10

[∵ 1-digit numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9]

**Ex 5.3 Class 8 Maths Question 5.**

If you have a spinning wheel with 3 green sectors, 1
blue sector and 1 red sector, what is the probability of getting a green
sector? What is the probability of getting a non-blue sector?**Solution:
**Total number of sectors are = 3 green + 1 blue + 1
red = 5 sectors

Probability of getting a green sector

Probability of getting non-blue sector

**Ex 5.3 Class 8 Maths Question 6.**

Find
the probabilities of the events given in Question 2.**Solution:****
**Refer
to Question 2, we have

(i) (a) Probability of getting a prime number

(ii) (a) Probability of getting a number greater than 5 = 1/6

(b) Probability of a number not greater than 5 = 5/6
