A dice is rolled. List the outcomes of the event A if:
A is the event that a number greater than or equal to 5 appears.

Answer

To solve the problem, we need to find the outcomes of the event A, where A is defined as the event that a number greater than or equal to 5 appears when a die is rolled.

### Step-by-Step Solution:

1. **Identify the total outcomes when a die is rolled**:
A standard die has six faces, numbered from 1 to 6. Therefore, the total outcomes when a die is rolled are:
\[ \{1, 2, 3, 4, 5, 6\} \]

2. **Define the event A**:
The event A is defined as the occurrence of a number that is greater than or equal to 5. This means we need to look for numbers in our total outcomes that satisfy this condition.

3. **List the numbers greater than or equal to 5**:
From the total outcomes, we identify the numbers that are greater than or equal to 5:
- The numbers are 5 and 6.

4. **Write the outcomes of event A**:
Therefore, the outcomes of event A, where a number greater than or equal to 5 appears, are:
\[ A = \{5, 6\} \]

### Final Answer:
The outcomes of the event A are \{5, 6\}.
