A drawer contains two coins: a fair coin and a two-headed coin. You choose one coin at random and flip it.
- If this first flip lands Heads, you flip the other coin for your second flip.
- If this first flip lands Tails, you flip the same coin again for your second flip.
What is the probability that the second flip lands Heads?
