Find the probability of getting head in a toss of one coin:

Answer

To find the probability of getting a head in a toss of one coin, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Sample Space**:
When we toss a coin, there are two possible outcomes: Heads (H) and Tails (T). Therefore, the sample space (S) can be represented as:
\[ S = \{H, T\} \]

2. **Count the Total Outcomes**:
The total number of outcomes in the sample space is 2, since there are two possible results when tossing a coin.

3. **Identify the Favorable Outcomes**:
We are interested in the event of getting a head. In the sample space, the favorable outcome for getting a head is:
\[ \text{Favorable Outcomes} = \{H\} \]
Thus, the number of favorable outcomes is 1.

4. **Calculate the Probability**:
The probability (P) of an event is calculated using the formula:
\[ P(\text{Event}) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}} \]
Substituting the values we found:
\[ P(\text{Getting Head}) = \frac{1}{2} \]

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