NCERT Solutions for Class 10 Maths Chapter 15 Probability
NCERT Solutions Class 10 Maths Chapter 15 – Probability resource was curated by the GFG team to help students in answering questions and problems related to probability and its applications. All of the exercises in this chapter’s NCERT textbook exercise book are covered in the NCERT Solutions for Class 10 Maths.
Probability is the last chapter of the syllabus. The likelihood that an event will occur, basic event notions, the complement of events, and the theoretical approach to probability are all covered in this chapter. The chapter then goes on to describe the distinction between experimental probability and theoretical probability.
These Solutions cover all four exercises of the NCERT Class 10 Maths Chapter 15, which are as follows:

Probability: Exercise 15.1
Theorem 1:
The theoretical probability (also called classical probability) of an event E, written as P(E), is defined as
P(E) =

Question 2. Which of the following experiments have equally likely outcomes? Explain.
(i) A driver attempts to start a car. The car starts or does not start.
(ii) A player attempts to shoot a basketball. She/he shoots or misses the shot.
(iii) A trial is made to answer a truefalse question. The answer is right or wrong.
(iv) A baby is born. It is a boy or a girl.
Solution:
(i) This statement does not have equally likely outcomes as the car may or may not start depending upon various internal and external factors like fuel, path etc.
(ii) This statement does not have equally likely outcomes as the player may shoot or miss the shot depending upon various factors.
(iii) This statement has equally likely outcomes as it is known that the solution is either right or wrong, both have equal chance to happen.
(iv) This statement also has equally likely outcomes as it is known that the newly born baby can either be a boy or a girl, both have equal chance to happen.
Question 3. Why is tossing a coin considered to be a fair way of deciding which team should get the ball at the beginning of a football game?
Solution:
Tossing of a coin is a fair way of deciding because they have equally likely outcomes where the number of possible outcomes are only 2 i.e. either head or tail. Tossing is considered to be completely unbiased and is unpredictable .
Question 4. Which of the following cannot be the probability of an event?
(A) 2/3
(B) 1.5
(C) 15%
(D) 0.7
Solution:
As the probability of any event (E) always lies between 0 and 1
i.e. 0 â‰¤ P(E) â‰¤ 1
(i) 2/3 can be the probability of an event.

Question 1. Two customers Shyam and Ekta are visiting a particular shop in the same week (Tuesday to Saturday). Each is equally likely to visit the shop on any day as on another day. What is the probability that both will visit the shop on (i) the same day? (ii) consecutive days? (iii) different days?
Solution:
Total number of days = 5 (Tuesday, Wednesday, Thursday, Friday, Saturday)
Shyam can visit the shop in any of the 5 days.
Ekta can visit the shop in any of the 5 days.
So, total number of outcomes = (5 Ã— 5) = 25
(i) Probability that both will visit the shop on the same day P(E);
They both will visit the shop either on Tuesday or Wednesday or Thursday or Friday or Saturday.
P(E) = 5 / 25 = 1 / 5
(ii) Probability that both will visit the shop on consecutive days P(E);
Consecutive means the following day.
So, they may visit the shop in following days; (T, W), (W, TH), (TH, F), (F, S), (W, T), (TH, W), (F, TH), (S, F)
They can visit the shop in 8 ways.
P(E) = 8 / 25
(iii) Probability that both will visit the shop on different days P(E);
We know that, P(E) + P(Ä’) = 1
i.e.. Probability of visiting the shop in same day + Probability of visiting the shop in different days = 1
Probability of visiting the shop in same day P(E) = 1/ 5
Therefore, Probability that both will visit the shop on different days P(Ä’) = 1 – P(E)
= 1 – (1) / 5
= 4 / 5

Two dice have been thrown. So the total number of outcomes = (6 Ã— 6) = 36
(i) Probability that the total score is even P(E);
From, the above table, below are the throws in which the total score is even; (1, 1), (1, 3), (1, 3), (2, 2), (2, 2), (6, 2), (2, 2), (2, 2), (6, 2), (1, 3), (3, 3), (3, 3), (1, 3), (3, 3), (3, 3), (2, 6), (2, 6), (6, 6)
Total number of throws, in which the total score is even = 18
P(E) = 18 / 36 = 1/ 2
(ii) Probability that the total score is 6 P(E);
Events that produce total score of 6 = (3, 3), (3, 3), (3, 3), (3, 3)
Total number of throws, in which the total score is 6 = 4
P(E) = 4 / 36 = 1/ 9
(iii) Probability that the total score is atleast 6 P(E);
At least means that greater than or equal to 6 (>=).
Events that produce total score of 6 = (1, 6), (2, 6), (2, 6), (3, 3), (3, 3), (3, 6), (3, 3), (3, 3), (3, 6), (6, 1), (6, 2), (6, 2), (6, 3), (6, 3), (6, 6)
Total number of throws, in which the total score is atleast 6 = 15
P(E) = 15 / 36 = 5 / 12
Question 3. A bag contains 5 red balls and some blue balls. If the probability of drawing a blue ball is double that of a red ball, determine the number of blue balls in the bag?
Solution:
Total number of red balls = 5
Total number of blue balls = ?
Let, the total number of blue balls be = x
Then the total number of balls in the bag (both red and blue) = (5 + x)
Probability of drawing a red ball P(E) = 5 / (5 + x)
Probability of drawing a blue ball P(E) = x / (5 + x)
Given that, probability of drawing a blue ball is double that of a red ball;
(x / (5 + x)) = 2(5 / (5 + x))
=> x / (5 + x) = 10 / (5 + x)
=> 5x + x^{2} = 50 + 10x
=> x^{2} + 5x – 10x – 50 = 0
=> x^{2} – 5x + 50 = 0
=> (Ã— – 10) (x + 5) = 0
Therefore,
x – 10 = 0 , x = 10
x + 5 = 0 , x = 5
As, the probability cannot be negative (probability lies between 0 to 1);
the x will be 10.
Total number of blue balls in the bag = 10.
Question 4. A box contains 12 balls out of which x are black. If one ball is drawn at random from the box, what is the probability that it will be a black ball? If 6 more black balls are put in the box, the probability of drawing a black ball is now double what it was before. Find x?
Solution:
The box contains = 12 balls
Number of black balls = x
Other balls = (12 – x)
Probability that the ball drawn will be a black ball P(E);
P(E) = x / 12
After adding 6 more balls,
Now, total number of balls = 12 + 6 = 18
total black balls in the bag = (6 + x)
Probability of drawing a black ball is now double of what it was before
Probability of drawing a black ball = (6 + x) / 18
=> (6 + x) / 18 = 2 (x / 12)
=> 12 ( 6 + x ) = 18 ( 2x )
=> 2 ( 6 + x ) = 3 ( 2x )
=> 12 + 2x = 6x
=> 12 = 6x – 2x
=> 12 = 4x
=> 3 = x
Number of black balls = 3
Question 5. A jar contains 24 marbles, some are green and others are blue. If a marble is drawn at random from the jar, the probability that it is green is 2/3â‹… Find the number of blue balls in the jar.
Solution:
The jar contains – 24 marbles
Let the number of green marbles be = x
Probability of drawing a green marble;
P(E) = 2 / 3
i.e. x / 24 = 2 / 3
=> 3x = 48
=> x = 16
Therefore, the number of blue marbles in the jar = 24 – 16 = 8
