RS Aggarwal Class 8 Maths Probability

RS Aggarwal Solutions for Class 8 provides different PDFs for every chapter, and all exercises are given separately in the chapter itself. Along with the textbook sums, several additional examples and other problems taken from previous question papers were also provided with this material. RS Aggarwal solutions-class 8 maths Chapter 25 Solutions helps students understand in a convenient language, and the downloading option of PDFs allows them to practice in their leisure time. Well-experienced mathematicians prepare these materials with the updated versions.

 

In this PDF, Probability Class 8 RS Aggarwal Solutions has provided a detailed explanation of probability. In simple words, it is explained as a chance of getting from the whole. The learning of this probability chapter may help the students in further classes as well as in their life also. All these sums given in the probability chapter are very reliable and natural, which can occur daily. So from any point, the Probability chapter is very important for the students, especially understanding not only in terms of marks.

 

The Probability chapter is concise, and it has just two exercises. But it plays a vital role and has a significant part in the question paper. RS Aggarwal Solutions Class 8 Chapter 25 explains the concepts of probability like introduction, definition, formulae, rules, etc.

 

All the Exercise questions with solutions in Chapter-25 Probability are given below:

  • Exercise (Ex 25A) 25.1

  • Exercise (Ex 25B) 25.2

  • Exercise 25A has around 12 questions. Each question has some sub-questions like solving the problem in multiple cases. All these questions are related to our regular usage items. For example tossing a coin, throwing a dice, picking a card from a pack, taking a ball from a bag or picking a fruit from a basket, etc. for all these questions RS Aggarwal Solutions explained a simplified method called considering the whole as a sum and then finding out the available chances for getting the required task. 

  • Exercise 25B is another exercise given in the chapter after explaining some extended topics and solved examples. It has eight questions, and each has four or five sub-questions. These questions are related to regular items like guessing the chance of getting a task from a spinning wheel, choosing a person from your class or a group. The questions mostly come under the probability chapter are not is or no type questions. The questions come under probability to help the students choose their goals or any other things when selecting from more options.


RS Aggarwal Class 8 Maths Solutions Chapter 25 encourages confidence in students' minds with the Probability chapter. This is an excellent chapter for the growing children whose habitat, long vision, spontaneousness, justification, etc. it is called a personality development chapter. Along with the two exercises, the RS Aggarwal Solutions for Class 8 also provides some additional problems and explains the weightage of marks in the examination.

 

RS Aggarwal Solutions for Class 8 Maths Probability explains the concepts of chapter, the importance of chapter, distribution, and weightage carried by the chapter in the exam and how the marks can be distributed for each sum. Like a few marks for formula, few marks for given data, few marks for calculation, etc. everything will be understood with RS Aggarwal Solutions. These PDFs can be taken from the official website of Vedantu to store for a future purpose.

 

Important Terminologies of Chapter 25, Probability for Class 8  are:

  • Chance: The situation that may or may not take place is referred to as chance.

  • Trial: It refers to an action that will result in one or more outcomes. For example, throwing two coins has four possible outcomes.

  • Random Experiment: An experiment in which the outcome of the trial cannot be predicted in advance.

  • Event: In a random experiment, the collection of outcomes based on a certain condition are known as an event.

  • Equally Likely Outcomes: when each outcome in an experiment has the same chance of occurrence, then it is known as an equally likely outcome.

  • Probability: The chance of happening an event is called probability. The value of probability always ranges from 0 to 1.

  • Elementary Event: It is the outcome of a random experiment.

  • Compound Event: When the event of a random experiment is dependent on two or more elementary events, then it is known as a compound event.

  • Experimental Probability: When the probability of an event is based on the actual experiments then it is known as experimental probability.

  • Theoretical Probability: When the probability of an event is determined without actually performing the experiment, it is known as theoretical probability.

  • Sample Space: It is a space in which all the possible events that might occur in a random experiment are listed.

  • Random Variables: The outcomes that can possibly occur in an experiment are denoted by random variables. These variables are of two types - discrete random variables and continuous random variables.

  • Discrete Random Variables: These variables denote distinct and countable values.

  • Continuous Random Variables: These variables can be used for infinite values.

  • Expected Value: The mean of a random variable, is termed as the expected value.

FAQs on RS Aggarwal Class 8 Mathematics Solutions for Chapter-25 Probability

1. A die is thrown. Find the probability of getting:

(i) 2 or 4

(ii) a prime number

(iii) a multiple of 2 or 3.

Let us consider a dice and write the available options. 

So, the possible outcomes recorded when a die is thrown are 1, 2, 3, 4, 5, and 6.

Let's take it as

Sample space: S = {1, 2, 3, 4, 5, 6}

Total number of outcomes = 6


(i) Let B be the event of getting a 2 or 4

And, Two or four occur once in a single roll.

A total number of favourable outcomes = 2.

Probability of getting 2 or 4 = P(B)= 2/6 = ⅓


(ii) Let P be the event of getting a prime number.

From the sample, we have 3 prime numbers (2, 3, 5)

Therefore, the number of favourable outcomes is 3.

So, the probability of getting a prime number :

P(P) = (Number of favourable outcomes)/ (Total number of outcomes) = 3/6 = ½


(iii) Let C be the event of getting multiples of 2 or 3.

From sample space, multiples of 2 are 2, 4, 6 and the multiples of 3 are 3 and 6.

Favourable outcomes from the sample set  = 2, 3, 4, and 6.

Probability of getting a multiple of 2 or 3 =

P(C) = 4/6 = ⅔

5. Why is chapter 25, that is, probability of class 8 mathematics important?

Chapter 25, that is, probability of class 8 mathematics is very important for students as this is the first time students are introduced to the concept of probability in their life. Therefore, it is very important for students to understand the concepts as well as the terms involved in probability. This chapter is essential as it is also dealt with in higher classes and in competitive exams as well. The questions from the concept of probability are also asked in the aptitude section of the college entrance examination and in the technical round of job interviews as well. Therefore, it is very important for students to clear the concepts of the chapter from the beginning only.
