Set of all possible outcomes of an experiment is called its

Options

A. universal set
B. sample space
C. partition
D. domain

Answer

To solve the question, we need to define the term that describes the set of all possible outcomes of an experiment.

### Step-by-Step Solution:

1. **Understanding the Experiment**:
- An experiment in probability refers to any procedure that can be infinitely repeated and has a well-defined set of possible outcomes.

2. **Identifying Outcomes**:
- For example, if we consider a simple experiment like tossing a coin, the possible outcomes are either "Head" (H) or "Tail" (T).

3. **Multiple Outcomes**:
- If we extend this to tossing two coins, the possible outcomes would be:
- HH (both coins show heads)
- HT (first coin shows heads, second shows tails)
- TH (first coin shows tails, second shows heads)
- TT (both coins show tails)

4. **Defining the Set of Outcomes**:
- The collection of all these possible outcomes from an experiment is what we refer to as a "sample space."

5. **Conclusion**:
- Therefore, the answer to the question "Set of all possible outcomes of an experiment is called its" is "sample space."

### Final Answer:
The set of all possible outcomes of an experiment is called its **sample space**.
