Question 309699: On certain day the chance of rain is 80% in San Francisco and 30% in Sydney. Assume that the chance of rain in the 2 cities is independent What is the probability that it will not rain in either city?

probability not rain in San Fransisco = 100% - 80% = 20% = 0.2
probability not rain in Sydney = 100% - 30% = 70% = 0.7

probability not rain in either city (the chance of rain in the 2 cities is independent) = 0.2 * 0.7 = 0.14 = 14%
