## Calculate each coin toss sequence probability:

Calculate the probability of the following coin flip

HTT

##### Coin Toss Probability Formula

Probability of each coin toss is 1/2, so we have:

 P(HTT)  = 1 x 1 x 1 2 x 2 x 2

 P(HTT)  = 1 8

P(HTT) = 0.125

Calculate the probability of the following coin flip

THT

##### Coin Toss Probability Formula

Probability of each coin toss is 1/2, so we have:

 P(THT)  = 1 x 1 x 1 2 x 2 x 2

 P(THT)  = 1 8

P(THT) = 0.125

Calculate the probability of the following coin flip

TTH

##### Coin Toss Probability Formula

Probability of each coin toss is 1/2, so we have:

 P(TTH)  = 1 x 1 x 1 2 x 2 x 2

 P(TTH)  = 1 8

P(TTH) = 0.125

## Calculate final probability:

 P(HTT + THT + TTH)  = 1 + 1 + 1 8

 P(HTT + THT + TTH)  = 3 8

P(HTT + THT + TTH) = 0.375

P(HTT + THT + TTH) = 0.375

### What 4 concepts are covered in the Coin Toss Probability Calculator?

coin
A unit of currency
coin toss probability
monte carlo simulation
a model used to predict the probability of a variety of outcomes when the potential for random variables is present.
probability
the likelihood of an event happening. This value is always between 0 and 1.
P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes
