To find the probability of getting exactly one head when tossing two coins, let's first consider the possible outcomes:
1. Heads, Heads (HH)
2. Heads, Tails (HT)
3. Tails, Heads (TH)
4. Tails, Tails (TT)
Out of these four outcomes, the outcomes that have exactly one head are:
- Heads, Tails (HT)
- Tails, Heads (TH)
This gives us 2 favorable outcomes.
The total number of possible outcomes is 4. Therefore, the probability of getting exactly one head is:
\[
\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{2}{4} = \frac{1}{2}
\]
Thus, the probability of getting exactly one head when tossing two coins is:
\(\frac{1}{2}\)
So the correct response is:
