20 POINTS On a certain day the chance of rain is 80% in San Francisco and 30% in Sydney. Assume the chance of rain in the two cities is independent. What is the probability that it will not rain in either city?

P(No rain in San Francisco AND No rain in Sydney)

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%

Step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
