Introduction
How a chance can be related to probability of the event?
Pre-Requisites:
Basic knowledge about probability
Activity:
The chance of the required sum to occur is low. Only in some cases we get the required sum. The chance of getting the required sum is equal in all cases. So they are equally likely
Real Life Question:
What is the result when a dice is rolled?
Key Words / FlashCards

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 occurrence of 2 is 1/36.
