For simplicity, rate earthquake intensities into low (L), medium (M), and high (H). The likelihoods of liquefaction associated with earthquakes of these intensities are, respectively, 0.05, 0.20, and 0.90. Assume that the relative frequencies of occurrence of earthquakes of these intensities are, respectively, 1, 0.1, and 0.01 per year. (a) What is the probability that the next earthquake is of low intensity
