What is the probability of getting exactly one head in two fair coin flips?

Explanation:
When you flip a fair coin twice, there are four equally likely results: heads-heads, heads-tails, tails-heads, and tails-tails. Exactly one head happens in two of these outcomes: heads-tails and tails-heads. So the probability is 2 out of 4, which equals 1/2. The other numbers come from other ideas: 1/4 would be if you counted only one specific outcome, and 3/4 is the chance of getting at least one head, not exactly one. The 1 would imply something always happens, which isn’t the case here.
