We all know that probability is one of the easiest chapters to learn and score marks in exams. But learning the chapter for some students can be a little bit tricky,  that is why RS Aggarwal notes class 7 chapter 22 probability helps students with a bunch of solutions, tricks and simple ways of learning that won't require any additional source of information and will also be efficient when recalling in times of need like exams or tests. RS Aggarwal notes are specially crafted for students to make them understand and make the learning process easier. You would not need any other source of information if you have these notes and you will surely excel in exams. These notes provide solutions to every sum in the textbooks and the solutions are pretty easily self-explanatory. Many people learn the notes by heart, but with these notes, it won’t be necessary at all. Students will learn how to solve sums and problems themselves.


Regarding the Chapter

A probability,  very basically and fundamentally, can be called the number that will reflect the chance or likelihood of a particular event and how and when it will occur. Probabilities can be expressed in a bunch of ways for easy understanding. It can be expressed from 0 to 1, 18 can be expressed from 0% to 100%. If in a problem or a situation the probability of an event to occur is zero then the event will not occur.  whereas if the probability of the event to occur is 1 then the event it is certain to happen. Let's say, the probability is 0.45 then in that case there are 45% chances out of a hundred of that event occurring.  When we look at it this way it might seem a little confusing for some students but it is not when you go ahead and do the exercises.  probability is one chapter that helps you to grow your rationale and cognitive abilities. 


Here are some applications of probability where you can predict the outcome in a certain way: 

  • Tossing of Coins

  • Drawing of Cards

  • Weather Forecast

  • Sports Strategies

  • Insurance Options

  • Games and Recreational Activities

1. What is Probability?

Probability is a measure of the possibility of an event to occur. Though for many events, probability cannot be predicted with full certainty, yet can predict the chance of an event to occur. The Probability can range anywhere in between 0 and 1, where 0 indicates no possibility of event occurrence and 1 indicates complete possibility of a certain event. 


Ex. When we toss a coin, there is a possibility of getting either a Head(H) or Tail(T). But when we toss two coins in the air, there are three possibilities of event occurrences: (H, H), (H, T),(T, T).

2. What is Empirical probability?

The term Empirical probability, relative frequency, or experimental probability of an event refers to the ratio of the no. of outcomes in which a specified event occurs to the total no. of trials, not in a theoretical sample space but an actual experiment. The Empirical probability uses the no. of occurrences of an outcome within a sample set as a ground basis for determining the probability of that outcome. The no. of times "event X" happens out of hundred trials will be the probability of event X happening.

4. What exactly are RS Aggarwal notes and how are they going to help with probability?

RS Aggarwal notes are keys and solutions to exercises from textbooks that explain the solution in a simple, efficient and easy way that will help students to understand the concept of probability better than they would normally.  These notes make you go deeper into the concept of probability and make you understand it in a way that is different from others and will help you to score well in your exams and tests.

5. Why is it important to learn probability?

Apart from being a concept that is easy to understand and also helps you score some easy marks in your exam, probability is a very useful concept in real life.  So do not think that by studying probability you are wasting your time at all,  instead think that you are investing your time in something that will give you good results now and even in the future. We use probability in our daily lives to make certain decisions when we don't know for sure what the certain outcome will be.  We perform probability actions in our daily lives without even realising it. This chapter helps us understand that thought process and takes us deeper into the concept.

6.  How is RS Aggarwal going to help me?

We talked about it earlier, RS Aggarwal notes are pretty useful and resourceful when it comes to solutions to textbook exercises and problems.  So there is that but apart from that, there is also the point that you need to take under consideration that these notes save a lot of your time by explaining new solutions in a simple and self-explanatory way that won't require assistance from any teacher or any other outside source.  RS Aggarwal notes,  once downloaded will always be there with you with easy accessibility and there will be no confusion because everything is pretty much organised.

7. How much importance does probability hold in examinations?
