2. A stock market trader buys 100 shares of stock A and 200 shares of stock B. Let X and Y be the price changes of A and B, respectively, over a certain time period. Assume the joint PMF of X and Y is uniform over the set of integers x and y satisfying -2 sxs 2, x - 1 sysx+ 1. Find the marginal PMF of Y.

Express the solution of the given IVP in terms of a convolution where g(t) is an arbitrary function.
Consider the graph of g(t) shown below. If the areas A, B and C are all defined to be the areas between the graph of g(t) and the x-axis and are, respectively, 7, 27 and 57, carefully sketch the graph of an antiderivative G(t) of g(t) satisfying G(0)=25. Label each critical point of G(t) with its coordinates. Then enter the critical points below, as a list of ordered pairs (that is, if you found critical points at x=2, y=3 and x=3, y=4, you would enter (2,3), (3,4)).
