Definition
What is it?
What is Possible? means thinking about all the things that CAN happen or CAN be done. It's about exploring the different outcomes or actions that are not impossible. We use it to understand what choices we have and what results we might get.
Simple Example
Quick Example
Imagine you are playing Ludo. When you roll the dice, what numbers are possible? You can get 1, 2, 3, 4, 5, or 6. You cannot get a 7 or a 0, because those are not possible outcomes for a standard dice roll.
Worked Example
Step-by-Step
Let's say you have a school bag with 3 different colour pens: 1 red, 1 blue, 1 green. You close your eyes and pick one pen.
---1. Identify the items: You have a red pen, a blue pen, and a green pen.
---2. Think about picking one item: You are picking just one pen.
---3. List all the pens you could possibly pick: You could pick the red pen. You could pick the blue pen. You could pick the green pen.
---4. State what is possible: It is possible to pick a red pen, a blue pen, or a green pen.
---Answer: Picking a red, blue, or green pen is possible.
Why It Matters
Understanding what is possible helps us make smart decisions and plan for the future. Scientists use it to predict weather, engineers use it to design safe buildings, and AI developers use it to create intelligent systems that can solve problems. It's key for careers in data science, engineering, and research.
Common Mistakes
MISTAKE: Thinking only about the most likely outcome | CORRECTION: Remember to list ALL possible outcomes, even if some are less likely.
MISTAKE: Including impossible things in the list | CORRECTION: Always check if an outcome can actually happen based on the rules or situation.
MISTAKE: Confusing 'possible' with 'certain' | CORRECTION: 'Possible' means it CAN happen, but it's not guaranteed. 'Certain' means it WILL happen.
Practice Questions
Try It Yourself
QUESTION: Your mom asks you to buy vegetables. You know the shop has tomatoes, potatoes, and onions. What vegetable is it possible for you to buy? | ANSWER: It is possible to buy tomatoes, potatoes, or onions.
QUESTION: You have a coin. If you flip it once, what are the possible outcomes? | ANSWER: The possible outcomes are Heads or Tails.
QUESTION: A traffic light can be Red, Yellow, or Green. If you are waiting at the signal, and it just turned from Red, what are the next two possible colours it could show? | ANSWER: After Red, it usually turns Green. After Green, it usually turns Yellow. So, Green and then Yellow are the next two possible colours.
MCQ
Quick Quiz
Which of these is a possible outcome when you roll a standard six-sided dice?
7
0
5
Chai
The Correct Answer Is:
C
A standard six-sided dice has faces numbered 1 to 6. So, 5 is a possible outcome. 7, 0, and Chai are not numbers on a standard dice.
Real World Connection
In the Real World
When you book a train ticket on IRCTC, the system shows you possible train routes, seat availability, and different timings. It calculates all the possible options based on your destination and date. This helps you choose the best possible journey.

OUTCOME: A result of an action or event | POSSIBLE: Something that can happen or be done | IMPOSSIBLE: Something that cannot happen or be done | CERTAIN: Something that will definitely happen

What to Learn Next
Now that you understand what is possible, you can learn about 'Probability'. Probability helps us calculate how likely each possible outcome is. It's the next step to becoming a super smart problem-solver!
