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.

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:
