• 0 heads, giving \(\{TT\}\) with \(n = 1\)

• 1 or more tails, giving \(\{HT, TH, TT\}\) with \(n = 3\)

• Exactly 1 head, giving \(\{HT, TH\}\) with \(n = 2\)

• 0 or 1 tail, giving \(\{HH, HT, TH\}\) with \(n = 3\)

Answer 1

“Only one head” means exactly one head. The two possible outcomes are \(HT\) and \(TH\).
