Calculate the probability of flipping 1 head and 2 tails

List out ways to flip 1 head and 2 tails
HTT
THT
TTH

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) = 1 8

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) = 1 8

P(THT) = 0.125

Calculate the probability of flipping a coin toss sequence of TTH
The probability of each of the 3 coin tosses 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
