State in each case, whether the given statement is true or false :
` [3,5] in [1,3,5,7,9]`

Answer

To determine whether the statement `[3, 5] in [1, 3, 5, 7, 9]` is true or false, we need to analyze the components of the statement.

### Step-by-Step Solution:

1. **Identify the Sets**:
- The first set is `[3, 5]`, which is a set containing the elements 3 and 5.
- The second set is `[1, 3, 5, 7, 9]`, which contains the elements 1, 3, 5, 7, and 9.

2. **Understand the Meaning of 'in'**:
- The notation `A in B` means that set A is an element of set B. In this case, we are checking if the set `[3, 5]` is an element of the set `[1, 3, 5, 7, 9]`.

3. **Check Membership**:
- The set `[1, 3, 5, 7, 9]` contains individual elements: 1, 3, 5, 7, and 9.
- However, it does not contain the set `[3, 5]` as a single element.

4. **Conclusion**:
- Since `[3, 5]` is not an individual element of the set `[1, 3, 5, 7, 9]`, the statement `[3, 5] in [1, 3, 5, 7, 9]` is **false**.

### Final Answer:
The statement `[3, 5] in [1, 3, 5, 7, 9]` is **false**.
