Question 3 [10 marks]. Suppose that X, Y and Z are statistically independent
random variables, each of them with a x²(2) distribution.
(a) Find the moment generating function of U = X + 3Y + Z. State clearly and
justify all steps taken.
(b) Calculate the expectation E(U) using the moment generating function.
Could you explain how to do part (c) please
Let X have a uniform distribution on (0,2) and let Y be independent of X with a uniform distribution over (0,3). Determine the cumulative distribution function of S=X+Y.

If an 8 or 2 is rolled, she loses her $9. This has a probability of J. If any other number is rolled, she does not win or lose, and the game continues. Find the expected value for Jessie on her first roll. Round to the nearest cent if necessary. Do not round until the final calculation. Provide your answer below:arrow_forward
