Answer
Success!
P(HTT + THT + TTH) = 0.375
↓Steps Explained:↓
Calculate the probability of flipping:
1 head and 2 tails
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

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

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 |
