2. The time between drought events at a certain region (in years) follows lognormal distribution. The probability that the time between 2 events exceeds 3 years is 50%, and the probability that it exceeds 1 year is 80%. a. Determine the mean and the standard deviation of log (to the base 10) of the time between drought events? b. What is the probability that the time between drought events exceeds 2 years?
