Cоlоrаdо "Wolf Creek Pаss" Snowfаll On February 18, 2026, the National Weather Service reported extreme snowfall at Wolf Creek Pass. Meteorologists are tracking 100 specific sensor stations across the Rockies to measure accumulation levels. Accumulation Level Northern Rockies Central Rockies Southern Rockies Total Over 24 inches 15 10 25 50 12–24 inches 10 15 5 30 Under 12 inches 5 10 5 20 Total 30 35 35 100 Using the table above, calculate the following probabilities. Write your answers as fractions, then decimal (proportion) and percent form. What is the probability a station recorded Over 24 inches of snow? What is the probability a station is in the Central Rockies AND recorded Under 12 inches? What is the probability a station is in the Northern Rockies OR recorded 12–24 inches? Given that a station is in the Southern Rockies, what is the probability it recorded Over 24 inches?
Sierrа Nevаdа "Frоzen Reservоir" Recоrds As of February 18, 2026, a series of powerful storms has brought up to 8 feet of snow to parts of the Sierra Nevada. The California Department of Water Resources (DWR) is monitoring 100 electronic sensor stations to track the "Snow Water Equivalent" (the amount of water the snow contains) across three key regions. Region High Accumulation Moderate Accumulation Low Accumulation Total Northern Sierra 22 8 5 35 Central Sierra 18 12 10 40 Southern Sierra 10 10 5 25 Total 50 30 20 100 Using the table above, calculate the following probabilities. Write your answers as fractions, then decimal (proportion) and percent form. What is the probability that a randomly selected sensor station recorded High Accumulation? What is the probability that a station is in the Central Sierra AND recorded Moderate Accumulation? What is the probability that a station is in the Northern Sierra OR recorded Low Accumulation? Given that a station is in the Southern Sierra, what is the probability it recorded High Accumulation?
