Solution
To solve the questions presented in the image, I need a bit more context, particularly about the random variables and . Specifically, I would need:
- The probability distribution or joint distribution of and .
- Information regarding whether they are discrete or continuous random variables.
Could you provide this additional context so I can help you solve the problems?
Here are the questions that are visible in the image:
- Find (Variance of ).
- Find (Expected value of ).
- Are and independent?
- Find (Covariance of and ).
- Find (Expected value of ).
- Find (Probability that equals ).
- Find (Probability that is greater than ).
Once you share the necessary details, I can walk you through the steps to solve each of them. Would you like to clarify or provide more information?

Formulas
Variance: V(X) = E(X^2) - [E(X)]^2
Expected Value: E(Y) = sum(y * P(y))
Covariance: Cov(X, Y) = E(XY) - E(X) * E(Y)
Probability: P(X = Y), P(X > Y)
