An online free coin toss probability Calculator assists you to find the probability of tossing a coin in just a blink of an eye. For that, you need to give the inputs in the below boxes and press the calculate button.

### How to Find the Probability of Coin Toss ?

Follow the steps which are showing below to calculate the probability of tossing a coin:

- When you toss a coin the possibility of getting a head is ½ and the possibility of getting a tail is also the same as a head.
- If you toss a coin n number of times the possibility of acquiring one head will be ½n.
- After that, for finding the possibility we need to apply the formula.
- Then, you will get the probability of possible outcomes.

### Example Problem for Coin Toss Probability

**Question: Find the probability of obtaining 3 heads when you toss a coin 5 times?**

**Solution**

Number of times you need to toss a coin (n) = 5

Total Possible outcomes = 2n= 25=2x2x2x2x2 = 32.

Total no.of favourable outcomes = 5C3 = 10

No.of heads = 3.

Let us use the probability formula,

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

probability = 10/32.

### FAQs on Coin Toss Probability Calculator

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

The possible outcomes when a coin is tossed 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 do I calculate the Probability?**

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

**3. What are the rules of Probability?**

- First Rule: Probability value should lie between 0 and 1.
- Second Rule: The sum of the probability of all possible outcomes should be equal to 1.
