The probaility of happening of an event can never be more than _______.

Answer

To solve the question "The probability of happening of an event can never be more than _______", we need to understand the fundamental principles of probability.

### Step-by-Step Solution:

1. **Understanding Probability**:
- Probability is a measure of the likelihood that an event will occur. It is expressed as a number between 0 and 1.

2. **Sample Space**:
- The sample space is the set of all possible outcomes of a random experiment. For example, when flipping a coin, the sample space is {Heads, Tails}.

3. **Sum of Probabilities**:
- The sum of the probabilities of all possible outcomes in a sample space is always equal to 1. This means that if you consider all possible events, their probabilities will total to 1.

4. **Individual Event Probability**:
- Since the sum of probabilities of all events is 1, the probability of any individual event must be less than or equal to 1. This is because if any event had a probability greater than 1, the total would exceed 1, which is not possible.

5. **Conclusion**:
- Therefore, the probability of happening of an event can never be more than 1.

### Final Answer:
The probability of happening of an event can never be more than **1**.
