Two days later, the National Hurricane Center projected the path of Isaac would pass directly over Cuba before reaching the Gulf of Mexico. Hurricanes that reach the Gulf of Mexico have a .08 probability of having passed over Cuba. Tropical storms that reach the Gulf of Mexico have a .20 probability of having passed over Cuba. How did passing over Cuba alter the probability that Isaac would become a hurricane by the time it reached the Gulf of Mexico? Use the above probabilities to answer this question. P(C|H) .08 (to 2 decimals) P(C|T) .20 (to 2 decimals) P(H|C) (to 4 decimals) c. What happens to the probability of becoming a hurricane when a tropical storm passes over a landmass such as Cuba? .
