1800-102-2727In the previous academic session, students were taught about the experimental probabilities of an event based on actual experiments' results. These were also referred to as experimental or empirical probabilities. Chapter 13-Probability provides a brief theoretical idea about the probability of an event, and this is done keeping in mind that all the occurrences are equally likely. The empirical probability of an event is represented as follows:
Similarly, the theoretical probability of an event, which is also referred to as the Classical Probability, is represented as follows:
An important note mentioned in Chapter 13-Probability that we must keep in mind while solving questions, is that the sum of the probabilities of all the elementary events is 1. This can also be used as a method of checking to see if the solution we calculate is correct or not. This chapter also includes a brief mention of complementary events and their representation. The different types of events are also mentioned in the chapter, namely, sure event, current event and impossible event.
Probability is a topic that holds great value in solving real-life problems and hence owns a heavy weightage. These vast applications of this topic in various fields like forecasts and predictions of weather, flood return patterns etc., makes it essential for students to understand thoroughly.
