NCERT Solutions for Class 11 Maths Chapter 14 Exercise 14.1

Above we discussed what you can expect in chapter 14 probability of class 11th Maths. How much important and difficult it will be in this academic year. But before you attempt 7 questions in exercise 14.1. You must know about the outcomes and sample space.

The result of an experiment or event is called outcomes. However, when you perform these sets of events many times and receive many outcomes randomly is called a sample of space-related to experiments/events.

Example 1 is about two coins, with a different value (one rupee and two rupees) tossed once. Now, you may find many combinations of outcomes. These all outcomes will be called a sample of space associated with the experiment.

Such examples are vital for you to study deeply to understand the process, events, etc. before you study events. Event is important and one of the major parts of the second part of chapter 16 probability from NCERT solutions for Mathematics class 11th.

Event can be understood by the experiment of tossing two coins and data recorded and illustrated in 11th Maths NCERT exercise 14.1. While the function of the event is much clearer in paragraph 14.2.1. Here, you will learn that if in sets of dice roll any outcome which is not you desired for will be called as an Event. In most of the questions of exercise 14.1, we have to find simple events. This will help to find probability of any case using simple definition.

For instance – Roll dice and your desired number is “2”. Now, when you rolled the dice, you get the outcome 1. This undesired outcome is event, but went ahead and threw 5 more times (3, 4, 5, 2, and 6) and finally got “2”.

All these outcomes when you threw the dice will be called sample space “S”. Here event will be denoted as “E”. If sample space is small and countable, student must write all the elements of sample space before solving the sum.
