Important Topics for RD Sharma Solutions for Class 8 Chapter 26: Data Handling-IV (Probability)

Introduction to Probability

Probability is used to evaluate the chance of the occurrence of a random event in an experiment. For example, if we roll a die then the likelihood of 3 coming on the top can be evaluated by the formula of probability. Since there are 6 possible outcomes that are possible, therefore the probability of 3 coming on top of the rolled die will be16. Therefore, with the knowledge of probability, we can mathematically calculate the likelihood that an event from a particular experiment will occur for certain or not.

The formula of probability is given as follows:

If the probability of an event is equal to 1, then the event is a sure or a certain event. If the probability of an event is 0, then the event is termed as an impossible event.

Some Basic Terms:

 

  • Random Experiment: The experiment under consideration of which the certainty of the results remain unknown and are found by the formulae and techniques of probability is termed as a random experiment.
  • Sample Space: In sample space, a set is created in which we list all the possible events that might occur in a random experiment.
  • Random Variables: We denote the outcomes that can possibly occur in an experiment using variables termed as random variables. Random variables are of 2 types:

 

  1. Discrete Random Variables: these variables are used to denote distinct and countable values.
  2. Continuous Random Variables: these variables can take up infinite values.
  1. Expected Value: If we find the mean of the random variables, it is termed as the expected value.
