A tropical storm is classified as major if it has sustained winds greater than 110 miles per hour. Based on data from the past t
wo decades, a meteorologist estimated the following percentages about future storms. • 20% of all tropical storms will originate in the Atlantic Ocean, of which 20% will be classified as major.
• 30% of all tropical storms will originate in the eastern Pacific Ocean, of which 15% will be classified as major.
• 50% of all tropical storms will originate in the western Pacific Ocean, of which 25% will be classified as major.
Based on the meteorologist’s estimates, approximately what is the probability that a future tropical storm will originate in the Pacific Ocean and be classified as major?
a. 0.045
b. 0.125
c. 0.17
d. 0.4
Based on the meteorologist's estimates, the probability of a future tropical storm to originate in the Pacific Ocean and be classified as major is c. 0.17
Explanation:
The total percentage of future tropical storm is 80% which is the sum of tropical storms in the eastern Pacific Ocean and the western Pacific Ocean. However, the problem asks for the total probability of being a major storm. In the eastern Pacific Ocean, it would be <u>0.045 which is 15% of 30</u> (total tropical storms in the eastern Pacific Ocean). In the western Pacific Ocean, it would be <u>0.125 which is 25% of 50</u> (total tropical storms in the western Pacific Ocean). The sum of both probabilities = 0.17, which is answer c.
Sydney and Darwin are 4,271 miles apart, Darwin and Perth are 1,645 miles apart, and Perth is 2,044 miles away from Sydney, making Darwin and Sydney the furthest distance.
