Topics Covered in Exercise 4.2 Class 8 Mathematics Questions
Before solving exercise 4.2 in NCERT solutions, students should take a look at the topics under Chance & Probability. All the topics of ex 4.2 are elaborated here for your reference.
1. 
Chance and Probability 


Chance and Probability
Probability indicates the degree of uncertainty. It is a measure of the probability of an event occurring.

Getting a result  When an experiment is conducted, the possible outcomes of the random experiment are referred to as outcomes. Ex. When we flip a coin, there are two possible outcomes: head or tail.

Equally likely outcomes  If all outcomes have the same possibility of occurrence, they are referred to as Equally likely outcomes. Ex. when conducting the random experiment, if we throw a dice, there is an equal probability for every no to appear, i.e., a single dice has the same chance of obtaining 1,2,3,4,5 and 6.

Linking chances to probability
Probability = Number of outcomes that make an event /Total number of outcomes of the experiment

Outcomes as events  Each outcome or set of outcomes obtained from an experiment is referred to as an event.
Probability = event/number of outcomes

Chance and probability related to real life
The use of probability is made in various cases in real life.

To find characteristics of a large group by using a small part of the group.

The Meteorological Department predicts weather by observing trends from the data over many years in the past.
