# Probability Calculator

The Probability calculator finds the probability of an event based on the favorable outcomes and the total outcomes. In mathematics, probability describes the occurrence of an event.

## What is a Probability Calculator?

Probability Calculator is an online tool that helps find an event's occurrence out of the total outcomes. It helps calculate the chance of an event in a few seconds. To use this ** probability calculator**, enter values in the input box.

## How to Use Probability Calculator?

Please follow the below steps to find the probability using an online probability calculator:

**Step 1:**Go to Cuemath’s online probability calculator.**Step 2:**Enter the favorable outcome and the total number of outcomes value in the input box of the probability calculator.**Step 3:**Click on the "Calculate" button to find the probability of an event.**Step 4:**Click on the "Reset" button to clear the fields and enter new values.

## How Probability Calculator Works?

The** Probability **of an event is defined as the ratio of favorable outcomes to the total number of outcomes. The probability of any event always lies between 0 and 1. To calculate the probability of any event we divide the favorable outcomes by the total number of outcomes.

## Solved Example on Probability

**Example 1:** What is the probability of selecting a black ball from a bag containing 4 yellow balls, 6 blue balls, 8 red balls, and 3 black balls? Verify it using the probability calculator.

**Solution:**

Total number of possible outcomes = 21

Favorable outcomes = 3

Probability = 3/21

Probability = 1/7 = 0.14

Thus, the probability of selecting a black ball from the given bag is 1/7 or 0.14

Similarly, to find the probability of an event, you can try the probability calculator for the following:

- Find out the probability of getting chocolate if the bag contains 10 chocolates and 5 toffees.
- What is the probability of getting 6 as a number when the dice rolled thrice?
