Problem 5 (20 points) The joint probability mass function of precipitation depth X (mm) at a rain gauge station and flow Y (m/s) of a nearby river is as follows: X=25 li Y=2 0.05 Y=4 0.11 Y=6 a. Confirm that this is a valid joint PMF (using its properties) b. Find the marginal PMFs of X and Y. c. If the rain gauge indicates a precipitation of 50mm, what is the probability that the flow exceeds 4 m3/s?
