NCERT solutions for Class 11 maths Chapter 16 Probability takes forward our journey into the world of probability with the introduction to axiomatic probability. students have already learned about classical probability where in order to obtain the probability of an event, we find the ratio of the number of outcomes favorable to the event, to the total number of equally likely outcomes. However, the utility of classical and statistical probability has got limitations when the number of outcomes is infinite, and to get over this limitation, axiomatic theory of probability was given in 1933 by A.N Kolmogorov, which is being explained in this NCERT solutions Class 11 maths Chapter 16 Probability

# Number of questions in each exercise of NCERT Solutions for Class 11 Maths Chapter 16 – Probability

The understanding of the sample space of outcomes and that the event is a subset of this sample space is fundamental to understanding the axiomatic approach to probability. Next is the understanding of set operations like union and intersection and then applying probability theory to it. The NCERT solutions class 11 maths Chapter 16 has tried achieving the objective of traversing the subject of probability by starting with a recap of the statistical probability and classical probability and then explaining the limitations of these two approaches, thereby explaining the necessity of the axiomatic probability. The chapter further then explains the various components of probability like sample space and the kind of events and how it is used to calculate probability.

The chapter explores the concept of sample space, sample points, events, and their types like impossible events, sure events and complementary events, set operations on events, mutually exclusive events, and then using all this foundation of events and sample space to find the probability using axiomatic concepts. The detailed formulas and facts regarding the same can be found in the pdf of the Class 11 maths NCERT solutions Chapter 16 Probability given below and also download the exercise-wise solutions provided in the links below.

It is because of practical considerations that the theory of probability was created. Somewhere in the 16th century, the first book around this concept was published. Thereafter it was worked upon by a number of mathematicians, eventually leading to probability as set functions and in the form which we use today. Thus, the students must ensure to imbibe the learnings from this chapter as this will help in competitive exams too. A brief segregation of the questions in each section of the NCERT solutions Class 11 Maths Chapter 16 Probability is given below :

# Important Topics and Subtopics of NCERT Solutions for Class 11 Maths Chapter 16 – Probability

Topics Covered: The Class 11 Maths NCERT solutions Chapter 16 covers a range of important topics such as the definition of sample space and sample points, different types of events like impossible, sure, complementary, mutually exclusive events, etc. Translation of operations of events using set theory and thus deriving the probability of union, the intersection of events is also discussed in detail.

Total Questions: Class 11 maths Chapter 16 Probability consists of 44 questions curated by the experts. Out of these, 28 are long answers, 8 are moderate, and 8 are easy problems. Apart from these, there are an extra 10 sums in the miscellaneous exercise.

The major topics and subtopics explained in Chapter 16 Probability of NCERT Solutions for Class 11, include

16.1 – Introduction

A brief description of the definition of probability and related terms is provided in this section. In simple terms, the probability is the ratio of the number of outcomes favourable to the event to the total number of outcomes. The related terms, viz. experiment, sample space, events, outcomes and so on.

16.2 – Random Experiments

16.2.1 Outcomes and sample space

The definition of random experiment subject to the required conditions and related terms are explained with examples such as tossing a coin and throwing a pair of dice so that students can easily grasp the concept.

16.3 – Event

16.3.1 Occurrence of an event

16.3.2 Types of events

16.3.3 Algebra of events

16.3.4 Mutually exclusive events

16.3.5 Exhaustive events

This topic has been explained with many examples and experiments to give a clear idea of the related terms and types of events. Algebra of events explains the intersection, union, difference and complement of events, etc.

16.4 – Axiomatic Approach to Probability

16.4.1- Probability of an event

16.4.2- Probabilities of equally likely outcomes

16.4.3 Probability of the event ‘A or B’

16.4.4 Probability of event ‘not A’.

Another way of describing the probability of an event is the axiomatic approach. This is well explained in Class 11 Maths Chapter 16 of the NCERT curriculum. Also, there are many examples and practice problems available to understand the concept easily.

The summary of the concepts explained in the NCERT Solutions of ANAND CLASSES’S are listed below

• A set of all possible outcomes is called sample space
• Sample points are the elements of sample space
• A subset of the sample space is called an event
• Impossible event: The empty set
• Sure event: The whole sample space
• Complementary event or ‘not event’: The set A′ or S – A
• Event A or B: The set A ∪ B
• Event A and B: The set A ∩ B
• Event A and not B: The set A – B
• Mutually exclusive event: A and B are mutually exclusive if A ∩ B = φ
• Exhaustive and mutually exclusive events

# List of Formulas in NCERT Solutions Class 11 Maths Chapter 16  – Probability

NCERT solutions Class 11 Maths Chapter 16 covers the probability of different types of events. Once we go through the basic understanding of sample space and the events, the different kinds of events based on their nature lead us to different probability axioms, which use set operations. In order to solve probability, one must go through some of the easy formulas from this chapter mentioned below:

1. Two events A and B are mutually exclusive events is A ∩ B = φ
2. Probability of an event P(A) = n(A)/n(S) where
• n(A) = number of elements in the set A
• n(S) = number of elements in set S
1. For any two events A and B , P(A or B) = P(A) + P(B) – P(A and B)
2. If A and B are mutually exclusive events then P(A or B) = P(A) + P(B)
