Compute conditional probability from finite sample space two coins are flipped; find P(two heads | at least one head).
Using a hint is okay. It just tells the trainer to give you a little more review.

1. List outcomes satisfying the condition.
2. List outcomes satisfying both target and condition.
3. Divide overlap count by condition count.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Denominator from the original full sample space.
