(Simulating a random vector) Explain how to simulate a random twodimensional vector 53' with a joint pdf f5, (:13) that is uniformly distributed in the shaded region. Assume that you have access to independent samples from a uniform distribution in [0, 1]. Explain your method, justifying why it works. Then implement it and submit the code along with a scatterplot of 1,000 samples. 0 0.25 0.5 0.75 1
