Transcribed Image Text:**Joint Probability Density Function Problem**
Consider the function \( f_{XY}(x,y) = c(x^2 + y^2) \), a joint probability density function over \( 0 < x < 5 \) and \( 0 < y < 5 \).
1. **Determine the value of \( c \)**:
Find the value of \( c \) that makes the function \( f_{XY}(x,y) \) a valid probability density function.
2. **Marginal Probability Density Function of \( X \), \( f_{X}(x) \)**:
Find the marginal probability density function of \( X \).
3. **Marginal Probability Density Function of \( Y \), \( f_{Y}(y) \)**:
Find the marginal probability density function of \( Y \).
4. **Joint Probability \( P(X > 2.5 \text{ and } Y < 1.5) \)**:
Calculate the probability that \( X \) is greater than 2.5 and \( Y \) is less than 1.5.
5. **Independence of \( X \) and \( Y \)**:
Determine whether \( X \) and \( Y \) are independent. You must demonstrate this using the formal definition.
6. **Correlation Between \( X \) and \( Y \)**:
Find the correlation between \( X \) and \( Y \).
7. **Conditional Probability**:
What is the probability that \( Y < 1.5 \) given \( X = 0 \)?
