RD Sharma Class 10 Maths Probability: Important Topics

The theory of probabilities is a challenging and interesting field of mathematics, and it also has great practical importance. Details of the concepts covered in this chapter are discussed below –


  • Probability — A Theoretical Approach


Here you learn that in a theoretical approach, the occurrence of any event is predicted without actually performing the experiment. It is assumed that the outcomes of an event are equally likely. We can associate the empirical interpretation of probability to all of those events whose outcomes can be determined by repeating the experiments for a large number of times. Here you also learn that the experimental probability of an event approaches its theoretical probability when the number of trials of an experiment is very large.

Empirical probability P(E) of an event E is given as – 

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

This section of the chapter also teaches you that the theoretical probability which is also known as the classical probability of an event E can be given as – 

P(E) = (Number of outcomes favourable to E) / (Number of all possible outcomes of the experiment)


  • Sum of Probabilities


You learn here that the sum of the probabilities of all the elementary events of an experiment is 1. This chapter further tells you that if E and Ē are complementary events then P (Ē) = 1 – P(E).


  • Impossible Event, Sure Event and Elementary Event


Further, you learn that the probability of an event which is impossible to occur is 0 and such an event is known as an impossible event. 

The probability of an event sure to happen with a value of 1  is called a sure event or a certain event. 

You come to know here that in general the probability of any event E is given by a number P(E) where 0 ≤ P (E) ≤ 1. 

Next, you learn that an elementary event is an event having only one outcome and the total of the probabilities of all the elementary occurrences together for an experiment come out to be 1.

This chapter also explicitly elaborates about complementary events and geometric probability. 

RD Sharma Class 10 Maths Chapter 13: Exercise-Discussion

After learning the topics given in the CBSE Class 10 Maths Syllabus, you must attempt to solve an ample number of questions from each topic to practice thoroughly. Our solutions for RD Sharma Class 10 Maths Chapter 13 exercises let you analyze your level of preparation and understanding of concepts. There are  2 exercises in this chapter. The components of the exercises are given below.

Exercise 13.1 

This exercise contains a total of 63 questions. Questions 1 to 9, 11 – 17 and 20 are direct questions asking you to determine probabilities of different experimental and real-life situations. Question 10 asks you to use your higher-order thinking skills to solve the problem based on numbers. Questions 18, 19 and 25 are based on probable combinations of playing cards. Question 21 asks you to use your higher-order thinking skills to solve the problem based on the game of chance. Questions 22 to 63 utilize your higher-order thinking skills for solving more complex questions based on the learnt concepts. 

Exercise 13.2

This exercise consists of 6 questions. All of these questions are based on geometrical figures and their parameters. These use your higher-order analytical skills to evaluate the information given and find out the required solution.
