2. A continuous random variable X has the probability density function tre fx (x) = for r 2 0, 0 otherwise. (a) Find the cumulative distribution function of X. (b) Calculate the expectation and the variance of X. (c) Determine the probability density function of X2. (d) Finally, suppose that X, and X2 are two independent random variables, each with the probability density function fx(x). Determine the probability density function of X1 +X2.Assessment to accompany Birt, Accounting: Business reporting for decision making Help | Salem Announcements Additional Question 7.1 Dowling Enterprises had the following information for the Financial year ending 30 June 2017.
