A die marked 1, 2, 3 in red and 4, 5, 6 in green is tossed. Let A be the event, the number is even, and B be the event, the number is red. Are A and B independent?

Explanation

To determine if events A and B are independent, we will follow these steps:

### Step 1: Define the sample space
The sample space \( S \) for a die marked with numbers 1 to 6 is:
\[ S = \{ 1, 2, 3, 4, 5, 6 \} \]

### Step 2: Define the events A and B
- Event A (the number is even):
