NCERT Solutions for Class 10 Maths Chapter 14 Exercise 14.1 Probability - PDF Download

1. Probability - A Theoretical Approach - In this chapter, theoretical probability will be studied in detail. Theoretical probability is a concept that describes the probability that an event is likely to occur. During these events, only the possible outcomes will be assumed, but no experiments will be conducted. Theoretical probability is also known as classical probability.

Here is the formula to calculate theoretical probability:

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

Events and Outcomes - Before we dive into probability, let’s first understand what events and outcomes are. An event is the outcome of an experiment. The outcome of an experiment is known as an event with possible outcomes. 

We have the following types of events and outcomes:

Types of Events

There are 5 types of events - Sure events (certain), Impossible events, Normal events, Complementary events, and Elementary events.

1. Sure Event (Certain Event) - A sure event is something that's always going to happen, irrespective of the other factors. For instance, if you get a number from 1 to 6, it's always going to be 1, so the probability of that happening is always 1.

                                            P(Sure Event) = 1 

2. Impossible Event - An Impossible event is something that can't happen. For example, if you want to get a number higher than 6, the probability of that happening is 0. So, the probability of an impossible event happening are always 0.

                                       P(Impossible Event) = 0

3. Normal Event - A normal event can be any event with a probability from 0 to 1 inclusive. It can also be a sure event or an impossible event. A normal event has a probability of 1/6 on a die.

                                      0 <= P(E) <= 1

4. Complementary event - An event is a complementary event if the probability of occurrence is equal to the probability of non-occurrence. The probability of obtaining a number that is less than 3 on a die is 2/6, and the probability of not obtaining a number less than3 is 4/6. Therefore, the sum of these probabilities is equal to one.

                                     P(E) + P(E’) = 1  

5. Elementary event - An elementary event is an event that has only one outcome. The probability of obtaining the number two on a die is equal to 1/6. Similarly, the probability of achieving the number one on a die is equivalent to 1/6 and the same for all other numbers. The sum of the probabilities of all elementary occurrences equals 1.

                                   P(E1) + P(E2) + P(E3) + … = 1

Types of Outcomes 

There are two different types of outcomes: equal likely outcome, and non-equally likely outcome. 

1. Equally Likely Outcome - An equally likely outcome is the outcome with the same outcome and probability. For Example, throwing a coin will result in an equal probability of either a head or a tail, with each of them having a probability of 1/2. 

2. Non-Equally likely outcome - An outcome that is not equally likely is an outcome that is uncertain in its results and dependent on a variety of other factors. For example, if a user attempts to start a vehicle, and the vehicle either begins or fails to start, this results in a non-equally likely outcome, as the vehicle will always begin unless it requires servicing or maintenance.
