Introduction
What is an event?
Pre-Requisites:
Basic knowledge about probability
Activity:
Let us say we require even number as sum. The probability of getting an even number as sum and the probability of getting an odd number as sum can be compared. The total sum of them both results in total probability which is 1.
Real Life Question:
What is the result when a dice is rolled?
Key Words / FlashCards

|---|---|
| Probability | The certainty of a desired outcome |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| dice | Take two dice and roll them. Note the sum of outcome every time and see how many times the desired outcome can occur. |
Real life uses :
Games, experiments, reliability, error, automation, scooter kick
Practical examples around us
| Examples | Explainations |
|---|---|
| Toss | The coin toss has an equal chance of a head and a tail as an outcome |
| Darts | In the darts game, the chance of hitting the bull is minimum. |
What you learn in Theory:
Everything is related to chance in its occurrence. Each event has a set of possible outcomes which has the same chance of happening. The probability when such events occur is the ratio of number of outcomes of particular event to number of outcomes of the experiment.
What you learn in Practice:
When two dice are rolled, any value ranging from 2 to 12 is likely to come with equal chance of occurrence. Thus this occurrence is equally likely. The probability of an even number occurring is more than the probability of odd number as the sum in this case.
