RD Sharma Solutions for Class 8 Maths - Data Handling IV - Free PDF Download

Probability is basically a concept or idea of chances of occurrence or non-occurrence of certain outcomes. A higher probability of occurrence means a higher outcome of happening and in that case, the numerical value of probability falls above zero. A numerical value below equal to zero or lower probability means a lower chance of occurrence. Usually, zero probability means no chance of occurrence and one means there is a certain chance of occurrence of the event.

Experts have worked hard to provide step-by-step answers to all important questions so that students can clear their doubts and revise the complete Syllabus and Score More marks by studying the solutions. A lot of exercises and practice problems are also provided so that the students can practice before their exams within a short time and Important Topics from the Data Handling Chapter

 

Probability plays a vital role in determining a research outcome, weather forecast, online games, determining blood groups and many more outcomes. Basically, this study of random events is able to give us an idea about a completely untold event. It helps us to remain well informed about an almost unknown event to us. This makes our journey easy since we can predict a risky event from beforehand.

 

Some important topics to remember in this Chapter of probability are summarized below:

  • Looking for data

  • Organising Data

  • Grouping Data

  • Bars with a difference

  • Circle Graph or Pie Chart

  • Drawing pie chartsChance and Probability

  • Getting a result

  • Equally likely outcomes:

  • Linking chances to probability

  • Outcomes as events

  • Chance and probability related to real life

Tips to Prepare for Exams Using RD Sharma Solutions of Class 8 Maths Chapter 26

Data handling is one of the important chapters in Class 8 Maths which has a higher weightage in board exams. So these tips will help students to secure good marks in their exams.

  • When collecting the data try to sort those in some order rather than just collecting randomly as this will help to present the data in quicker time in charts or tables.

  • Read the questions carefully before answering, sometimes the question says to present the data in graphs or charts if we are not clear with graphs and chart then we may end up with wrong answers.

  • Try using geometrical tools while plotting graphs and charts so that the answer looks clean and tidy which increases the presentation skills.


Conclusion

Students will find it easy when studying using RD Sharma Class 8 Data Handling solutions prepared by Vedantu as the solutions are explained in a step by step manner. The experts have done a lot of research on the solutions so that students will enjoy reading the RD Sharma solutions. The free PDF also provides wide varieties of exercise problems for students to prepare and improve their subject knowledge.

FAQs on RD Sharma Class 8 Maths Solutions Chapter 26 - Data Handling IV (probability)

1. What is probability according to chapter 26 of class 8 Maths?

Probability is the branch of statistics that deals with the chances of occurrence and non-occurrence of some random events. It gives us an idea about the certainty and uncertainty of events with a numerical value ranging from zero to one. We can predict from the numerical values whether an event will actually even occur or not. A lower probability close to zero gives us an idea that there is no chance of the event to occur whereas a higher probability shows a chance to occur. The numerical value of one tells that the event is certain to happen.

2. What is the importance of probability in real life as taught in chapter 26 of class 8 Maths?

Probability plays a vital role in normal day-to-day life. Starting from predicting the weather before planning for a picnic to predicting which party will rule in politics based on probable votes all depends on the concept of probability. One in business has to think about the probability of sales of his goods. Industries like insurance companies all run on the basis of probability. One has to think about the probability of an accident or disease before buying health insurance, or the chance of having damage to the car before buying car insurance. Gambling is totally based upon probability. So the probability is so much linked to our day-to-day life that we totally rely on probability for deciding safe choices.

3. Why is probability included in the Class 8 Maths curriculum?

It is important for a Class 8 student to build an idea about the chances of occurrence of different events in day-to-day life. Learning probability will make them understand the different variations of life and they will know how to accept them and prepare themselves as well-informed citizens in the future world. This study will also prepare them for the understanding of risk, relative risk or no risk events. This study is also helpful to students for preparing a particular topic for the exam based on the chances of coming up with the topic in the exam.

4. According to chapter 26 of Class 8 Maths, how to determine probability in data handling?

Probability is actually determined by dividing the number of favourable outcomes by the number of all possible outcomes of a particular event. It is determined stepwise as follows:

  •  Identify a single event with a single outcome

  • Determine all the feasible outcomes that can occur

  • Divide the number of such events by the number of all feasible outcomes.

  • Determine the probability

When there are multiple random events probability is then determined as follows:

  • Identify each event to be calculated

  • Probability for each and every single event to be calculated

  • Finally, all probabilities are multiplied by each other. 

5. What are the different resources used in probability as discussed in chapter 26 of class 8 Maths?

The different resources used in probability can be summed as follows:

  • Samples

  • Events

  • Random Variables

  • Expected values

  • Independent events

  • Dependent events

  • Variance

  • Mean

  • Theoretical probability

  • Experimental probability

  • Conditional Probability

  • Tree Diagram
