Write each of the following sets in Roster form:
B = set of all whole number less than 8.

Answer

To write the set of all whole numbers less than 8 in roster form, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Whole Numbers**:
Whole numbers start from 0 and go on indefinitely (0, 1, 2, 3, ...).

2. **Identify the Range**:
The question asks for whole numbers that are less than 8. This means we need to consider whole numbers starting from 0 up to, but not including, 8.

3. **List the Whole Numbers**:
The whole numbers less than 8 are:
- Start from 0: 0
- Then 1: 1
- Then 2: 2
- Then 3: 3
- Then 4: 4
- Then 5: 5
- Then 6: 6
- Finally, 7: 7

4. **Write in Roster Form**:
Now we can write these numbers in roster form, which is a way of listing the elements of a set within curly braces.

Therefore, the set B in roster form is:
\[ B = \{0, 1, 2, 3, 4, 5, 6, 7\} \]

### Final Answer:
B = {0, 1, 2, 3, 4, 5, 6, 7}
