Which of the following is wrong in case of representation of probability in percentage

Options

A. Less than 100
B. Less than 0
C. Less than 1
D. Equal to 0

Answer

To solve the question regarding which representation of probability in percentage is wrong, we need to analyze the options provided based on the fundamental principles of probability.

### Step-by-Step Solution:

1. **Understanding Probability**:
The probability of an event is defined as the ratio of the number of favorable outcomes to the total number of outcomes. Mathematically, it is expressed as:
\[ P(E) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}} \]
The value of probability \( P(E) \) ranges from 0 to 1.

2. **Converting Probability to Percentage**:
To express probability as a percentage, we multiply the probability by 100. Therefore, the range of probability in percentage is from 0% to 100%.

3. **Analyzing the Options**:
- **Option 1**: Less than 100% - This is valid because probabilities can be less than 100%.
- **Option 2**: Less than 0% - This is invalid because probabilities cannot be negative. A probability less than 0% implies a negative probability, which is not possible.
- **Option 3**: Less than 1% - This is valid because probabilities can be less than 1 (or 1%).
- **Option 4**: Equal to 0% - This is valid as it represents an impossible event.

4. **Conclusion**:
The only incorrect representation of probability in percentage is **Option 2: Less than 0%**.

Thus, the answer to the question is that the wrong representation of probability in percentage is **Option 2**.
