### Problem Statement To understand the proper formulation and properties of probability distributions, consider the following tasks: 1. **Calculate \( c_{\rho} \) so that \( f_{X}(x) \) is a valid Probability Density Function (PDF).** - A valid PDF must satisfy the properties of being non-negative and integrating to 1 over its entire range. 2. **Find the Cumulative Distribution Function (CDF) of \( X \) parameterized by \( \rho \).** - The CDF, \( F_{X}(x) \), represents the probability that the random variable \( X \) is less than or equal to a certain value \( x \) and is derived by integrating the PDF over the relevant range. 3. **Find \( P(2 < X \leq 4) \).** - This probability can be found by evaluating the CDF at the boundaries of the interval and subtracting the values: \( F_{X}(4) - F_{X}(2) \). These tasks will help in understanding the fundamental concepts of the Probability Density Function, Cumulative Distribution Function, and the application of these concepts to determine probabilities over specific intervals.

## Power Laws A random variable \( X \) follows the power law with parameter \( \rho > 0 \) when \( X \) has Probability Density Function (PDF) \( f_X(x) = c_{\rho} x^{-\rho} \) for \( x \ge 1 \), where \( \rho \) governs how fast the probabilities go to 0 as \( x \) goes to \( \infty \).
