Let A = [2,4,6,8 ],B = { 6,8,10 ,12} and C = {7,8,9,10 } Find .
` B nn C `

Answer

To find the intersection of sets B and C, we will follow these steps:

### Step 1: Identify the elements of each set
- Set B = {6, 8, 10, 12}
- Set C = {7, 8, 9, 10}

### Step 2: Determine the common elements
We need to find the elements that are present in both sets B and C.

- Check each element of set B:
- **6**: Not in set C
- **8**: Present in set C
- **10**: Present in set C
- **12**: Not in set C

### Step 3: List the common elements
From our checks:
- The common elements between sets B and C are **8** and **10**.

### Step 4: Write the intersection
The intersection of sets B and C, denoted as B ∩ C, is the set of common elements:
- B ∩ C = {8, 10}

### Final Answer
B ∩ C = {8, 10}
