Our coin flip probability calculator is a free online tool that finds a probability of a coin. All you need to do is give the no. of heads and the no. of flips as inputs and get the output by pressing the calculate button.

### Steps to Find the Probability of Coin Flip

Go through the guidelines which are shown below to find the probability of flipping a coin:

- Firstly, write down all the values which are given in the problem.
- Then you need to find the total possible outcomes and then find the no. of favorable outcomes.
- After that, apply the probability formula.
- Then, you will get the possible outcomes.

### Coin Flip Probability Example

**Example**

**Question: Find the probability of obtaining 4 heads when you flip a coin 10 times?**

**Solution**

Number of times you need to flip a coin (n) = 10

Total Possible outcomes = 2n= 210=2x2x2x2x2x2x2x2x2x2 = 1024.

Total no.of favourable outcomes = 10C4 = 201

No.of heads = 4.

Let us use the probability formula,

**Probability = no of favorable outcomes/ total number of possible outcomes**

probability = 201/1024.

### FAQs on Coin Flip Probability Calculator

**1. What is the probability of obtaining a tail when we flip a coin?**

The possible outcomes when a coin is flipped are 2, i.e. head or tail. The probability of getting a tail when a coin is tossed is 1/2 or 50%.

**2. How to calculate the Probability?**

Probability can be calculated using the formula, probability = No. of favorable outcomes/ total no.of possible outcomes.
