In a region three hazards can occur annually: flood (probability 0.12, impact 7), landslide (probability 0.08, impact 9) and drought (probability 0.15, impact 5). If a flood occurs in a given year, the probability of landslide that year increases by 50 % of its original probability, and the probability of drought decreases by 20 % of its original probability. The expected annual hazard risk index is defined as the sum over hazards of (probability × impact). Compute the expected annual hazard risk index taking the conditional effect of flood into account.
