How to Use This Probability Calculator
Using the Probability Calculator is very simple.
Just follow these steps:
- Enter the number of favourable outcomes (the results you want)
- Enter the number of total possible outcomes
- Click the Calculate button
- See your probability result instantly
That’s it. No complicated steps. No math stress.
How the Calculation Works (Simple Explanation)
Probability tells us how likely something is to happen.
We use this simple formula:
Probability = Favourable Outcomes ÷ Total Possible Outcomes
Let’s look at an easy example.
Imagine you roll a normal dice.
- A dice has 6 total sides
- You want to know the chance of rolling a 3
- There is 1 side with the number 3
So the probability is:
1 ÷ 6 = 0.1667
This means there is about a 16.67% chance of rolling a 3.
Our calculator does this math for you in seconds.

FAQs About Probability Calculator
What is probability in simple words?
Probability tells us how likely something is to happen. It is usually written as a number between 0 and 1 or as a percentage.
Can probability be more than 1?
No. Probability cannot be greater than 1. If something is certain to happen, its probability is 1 (or 100%).
What does a probability of 0 mean?
It means the event cannot happen. It is impossible.
Is this calculator good for homework?
Yes. It helps students check answers and understand how probability works. But it’s also important to learn the steps, too.
Does this work for games like cards and dice?
Yes. You can use it for dice, cards, coins, and many other simple probability problems.
