![**Problem 2: Understanding Independent Continuous Random Variables**
Consider two independent continuous random variables, \( X \) and \( Y \). Their respective probability density functions are defined as follows:
\[
f(x) =
\begin{cases}
1, & 0 < x < 1 \\
0, & \text{otherwise}
\end{cases}
\]
\[
f(y) =
\begin{cases}
8y, & 0 < y < 0.5 \\
0, & \text{otherwise}
\end{cases}
\]
**Objective:**
Determine the probability \( P(X > Y) \).
**Explanation of Graphs/Diagrams:**
- The density function \( f(x) \) describes a uniform distribution for \( X \) over the interval (0, 1), meaning that all values of \( x \) in this range are equally probable.
- The density function \( f(y) \) indicates a triangular distribution for \( Y \) on the interval (0, 0.5), peaking at \( y = 0.5 \). The function linearly increases from 0 to 0.5 following the expression \( 8y \). Beyond this range, the probability density is zero.
**Inquiry:**
The task is to calculate the probability \( P(X > Y) \), where \( X \) is greater than \( Y \). This involves integrating the joint density function over the region where \( X > Y \) within their respective ranges.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff0d90012-896b-4f52-8f0b-e38034636c35%2F599224cd-943d-42bb-91de-c6cc03f16e9b%2Flqiymwn_processed.png&w=3840&q=75)
