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
