Coin Toss Probability Calculator

The coin toss probability refers to the probability of getting exactly 'h' number of heads/tails in the 'N' number of a coin toss. A coin toss is an independent event getting heads/tails in one trial does not affect the outcome of other trials.

How to Use Coin Toss Probability Calculator?

Please follow the below steps to find the coin toss probability:

• Step 1: Enter the number of desired heads and the number of a coin toss in the given input boxes.
• Step 2: Click on the "Calculate" button to find the probability.
• Step 3: Click on the "Reset" button to clear the fields and enter the different values.

How to Find a Coin Toss Probability?

As the outcomes of a coin toss are independent so, the total number of outcomes will be equal to the total number of trials times the number of possible outcomes in a single trial i.e. 2, and the number of favorable outcomes will be equal to the number of possible favorable combinations.

Here n is the total number of trials and h is the number of heads in the n number of trials.

Solved Example:

What will be the probability of getting 4 heads in 6 coin tosses?

Solution:

Number of trials (n) = 6

Total possible outcomes = 2ⁿ = 2⁶ = 64

Number of heads (h) = 4

Total number of favourable outcomes = ⁶C₄ = 15

Now probability = 15/64 = 0.234
