In RD Sharma Solutions for Class 7 Mathematics Chapter 25 data handling IV, students study all the topics related to probability, such as a trial, event, and experiment. Let's go through some of the key topics discussed in this Chapter.

• Probability's definition and meaning- A probability is a number that reflects the chance or likelihood that a particular event will occur.

• Definition of trial- A trial is a series of actions that result in one or more outcomes.

• Definition of event- An event is an outcome or defined collection of outcomes of a random experiment.

• Random experiment- A random experiment is one in which the outcome of a trial cannot be predicted ahead of time.

• Happening of an event- If any of the outcomes satisfying the definition of the event occurs as a result of the experiment when it is carried out, the event is said to have happened.

• Empirical probability- The empirical probability of occurring of an event E is illustrated as:

P(E) = Number of trials in which the event occurred / Total number of trials

Mathematical Definition of Probability

Probability is a measure for determining the possibility of an event occurring. Many things are impossible to forecast with 100% accuracy. Using it, we can only anticipate the probability of an event occurring, i.e. how probable it is to occur. Probability can range from 0 to 1, with 0 indicating an uncertain event and 1 indicating a certain event. Probability or Data Handling for Class 7 is an important topic for students because it teaches all of the basic ideas. In a sample space, the probability of all events adds up to 1.

Formula of Probability

Probability of an event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
