Based on its data, the USGS has calculated the probability of a natural hazard occurring in any given year that would cause 10 or more fatalities. The following table lists the probabilities for the four most commonly occurring natural hazards. Event Probability of an annual event with ≥10 fatalities in the United States Earthquake 0.11 Hurricane 0.39 Flood 0.86 Tornado 0.96 0 = no chance of occurring / 1 = 100% chance of occurring What is the probability of a hurricane and a tornado, each causing 10 or more fatalities, both occurring in the same year? A. 0 B. 0.37 C. 0.96 D. 1.35
