When you toss a fair coin two times, each toss has two possible outcomes: heads (H) or tails (T). The sample space includes all possible combinations of outcomes for the two tosses.

Possible Outcomes:

1. First toss: Heads (H), Second toss: Heads (H) — Result: HH
2. First toss: Heads (H), Second toss: Tails (T) — Result: HT
3. First toss: Tails (T), Second toss: Heads (H) — Result: TH
4. First toss: Tails (T), Second toss: Tails (T) — Result: TT

Sample Space:

$\text{Sample Space} = \{HH, HT, TH, TT\}$

Answer:

The correct answer is b. {HH, HT, TH, TT}.

Tip: Always ensure you list all possible outcomes in a sample space to avoid missing any potential event!
