Write the following sets in set builder form :
B = {all months of a year}

Answer

To write the set B = {all months of a year} in set builder form, we follow these steps:

### Step 1: Identify the Elements of the Set
The elements of the set B are the months of the year. These are:
- January
- February
- March
- April
- May
- June
- July
- August
- September
- October
- November
- December

### Step 2: Define the Variable
We will use a variable to represent the elements of the set. Let's use 'x' to denote any month.

### Step 3: Write the Condition
We need to express the condition that 'x' is a month of the year. This can be stated as:
- x is a month.

### Step 4: Combine the Variable and Condition
Now we can combine the variable and the condition to form the set builder notation. The set builder form will be:
B = { x | x is a month of the year }

### Final Answer
Thus, the set B in set builder form is:
B = { x | x is a month of the year }
