Challenge Problems
Push your limits with challenges.
Question 1
Suppose a discrete random variable has a PMF given as P(X=1) = 0.1, P(X=2) = 0.2, P(X=3) = 0.4, and P(X=4) = 0.3. Construct the corresponding CDF and explain the interpretation.
💡 Hint: Add the PMF probabilities cumulatively to form the CDF.
Question 2
Consider a scenario where the CDF of a random variable is defined piecewise. Describe how this affects the PMF.
💡 Hint: Analyze the areas where the CDF changes values.
