(b) Plot the probability distribution of the annual change in storage. (0) If [31 = 100,000, (11 = 20,000, [32 = 70,000 and (12 = 50,000, what is the probability that the change in storage will be 1) negative and ii) greater than 15,000 acre-feet? 2.11 The annual inow into a reservoir (acre-feet) follows a probability density given by px(x) = 1/ (I3 1 - (11). The total annual outow in acre-feet follows a probability distribution given by py(y) = l/(Bz - (12). Consider that B1 >132 and (11
