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 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.
Coin Toss Probability = nCh/2n
Here n is the total number of trials and h is the number of heads in the n number of trials.
What will be the probability of getting 4 heads in 6 coin tosses?
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
