The joint probability distribution of precipitation X (inches) and runoff Y(cfs) (discretized here for simplicity) due to storms in the Lower Kaskaskia Valley is as follows: (refer to picture) (a) What is the probability that the next storm will bring a precipitation of 2 or more inches and a runoff of more than 20 cfs? (b) Are X and Y statistically dependent? Substantiate your answer. (c) Determine and plot the marginal PMF of runoff. (d) Determine the correlation coefficient between X and Y.
