When you toss a coin twice, the sample space is the set of all possible outcomes for this experiment. Each toss has two possible outcomes: heads (H) or tails (T). Therefore, for two tosses, the sample space will include all combinations of these outcomes.

The sample space is:

$S = \{ (H,H), (H,T), (T,H), (T,T) \}$

This means:

• $(H, H)$ represents heads on both tosses.
• $(H, T)$ represents heads on the first toss and tails on the second toss.
• $(T, H)$ represents tails on the first toss and heads on the second toss.
• $(T, T)$ represents tails on both tosses.

3. How would the sample space change if the coin is tossed three times?
4. What is the probability of getting at least one tail when tossing a coin twice?
5. How many possible outcomes are there if a coin is tossed four times?

Tip: The size of the sample space for tossing a coin $n$ times is $2^n$, since each toss has two possible outcomes.
