Important Topics in Class 9 Maths Chapter 15 Probability are elaborated below:

Probability – An Experimental Approach

Experimental Probability can be defined as the branch of mathematics that deals with the uncertainty of the occurrence of events. Its calculation can be done by dividing the number of times an event has taken place by the number of trials in an experiment.

The formula of Experimental Probability is = Number of times a particular event occurs/ Number of total trials)

Probability — A Theoretical Approach

Theoretical Probability can be defined as the probability of the occurence of certain events that are not present in an experimental way.

The formula of Theoretical Probability is = Total number of desired outcomes/ Total number of outcomes
