AI Generated Solution

To solve the problem of finding the variance of the number of successes when a die is tossed twice, we can follow these steps: ### Step-by-Step Solution: 1. **Define the Random Variable**: Let \( X \) be the random variable representing the number of successes (even numbers) when a die is tossed twice. The possible values of \( X \) are \( 0, 1, \) or \( 2 \). 2. **Identify the Number of Trials and Probability of Success**: ...
