When an unbiased coin is tossed, the probability of getting a head is ______.

Answer

To find the probability of getting a head when an unbiased coin is tossed, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Total Outcomes**:
When an unbiased coin is tossed, there are two possible outcomes: Heads (H) and Tails (T).
- Total outcomes = 2 (H, T)

2. **Identify the Favorable Outcomes**:
We are interested in the event of getting a head. There is only one favorable outcome for this event.
- Favorable outcomes = 1 (H)

3. **Use the Probability Formula**:
The probability (P) of an event is calculated using the formula:
\[ P(\text{Event}) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Outcomes}} \]

4. **Substitute the Values**:
Now, substitute the values we identified into the formula:
\[ P(\text{Getting a Head}) = \frac{1}{2} \]

5. **Final Answer**:
Therefore, the probability of getting a head when an unbiased coin is tossed is:
\[ \frac{1}{2} \]
