A road is likely to be flooded such that not more than one flood occurs during a year. The level of the road is raised so that the chance that it is flooded at least once during a 10-year period is 15%. a. Let X be the number of years until a critical event resulting in road flooding occurs. What probability distribution is appropriate to model X? b. On average, what is the expected return period between critical events that causes flooding on the road? [Meaning: What is the expected value of X?]
