__Calculate each coin toss sequence probability:____Calculate the probability of flipping a coin toss sequence of HTT__The probability of each of the 3 coin tosses is 1/2, so we have:

P(HTT) = | 1 x 1 x 1 |

| 2 x 2 x 2 |

P(HTT) =

**0.125**__Calculate the probability of flipping a coin toss sequence of THT__The probability of each of the 3 coin tosses is 1/2, so we have:

P(THT) = | 1 x 1 x 1 |

| 2 x 2 x 2 |

P(THT) =
