Answer

To solve the problem of finding the number of ways to select at most 1 T-shirt from a shelf of 10 identical red T-shirts, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Problem**: We have 10 identical red T-shirts, and we want to find the number of ways to select at most 1 T-shirt. "At most 1" means we can either select 0 T-shirts or 1 T-shirt.

2. **Calculating the Ways to Select 0 T-shirts**:
- There is only 1 way to select 0 T-shirts, which is to not select any T-shirt at all.
- **Ways to select 0 T-shirts = 1**.

3. **Calculating the Ways to Select 1 T-shirt**:
- Since all T-shirts are identical, there is also only 1 way to select 1 T-shirt from the shelf.
- **Ways to select 1 T-shirt = 1**.

4. **Total Ways to Select T-shirts**:
- Now, we add the number of ways to select 0 T-shirts and the number of ways to select 1 T-shirt:
\[ \text{Total Ways} = \text{Ways to select 0 T-shirts} + \text{Ways to select 1 T-shirt} = 1 + 1 = 2. \]

5. **Conclusion**: Therefore, the total number of ways to select at most 1 T-shirt from the shelf is **2**.

### Final Answer:
The number of ways of selecting at most 1 T-shirt is **2**.
