Probability | NCERT Class 10 Maths
In the introduction, the concept of experimental or empirical probabilities is explained first. Following this, a theoretical approach to probability is presented and it is mentioned that theoretical probability is also known as classical probability. Further, the formula for theoretical probability is presented as the division of the number of outcomes favourable to an event E by the of all possible outcomes of the experiment. Also, it is observed that the sum of the probabilities of all the elementary events of an experiment is 1. Further to this, concepts like impossible events, sure or certain, and complementary events are explained.
