A die is rolled. List the outcomes of the event A if:
A is the event that a number not less than 3 appears.

Answer

To solve the problem, we need to determine the outcomes of the event A when a die is rolled, where event A is defined as the occurrence of a number not less than 3.

### Step-by-Step Solution:

1. **Identify the Sample Space**:
When a die is rolled, the possible outcomes (sample space) are the numbers 1 through 6.
- Sample Space (S) = {1, 2, 3, 4, 5, 6}

2. **Define the Event A**:
The event A is defined as the occurrence of a number not less than 3. This means we need to find all the numbers in the sample space that are equal to or greater than 3.

3. **List the Outcomes**:
From the sample space, we identify the numbers that are not less than 3:
- The numbers are: 3, 4, 5, and 6.

4. **Write the Outcomes of Event A**:
Therefore, the outcomes of event A are:
- A = {3, 4, 5, 6}

### Final Answer:
The outcomes of event A, where a number not less than 3 appears when a die is rolled, are:
- A = {3, 4, 5, 6}
