Unformatted text preview: t . If X t , Alvin gets a score of S = 1/ X . Otherwise his score is S = 0. Find the cdf of S . Is S a continuous random variable? 3. Let X be a uniform (0, 1) random variable. Compute g[G ] and then check the result by using the definition of expectation. 4. Let X be uniformly distributed on the interval (0, 1). Find the density function of = G / where 0. 5.
