Dan and Glenn are swimming buddies who love to challenge themselves while diving. The amount of time Dan can hold his breath underwater, D, is 111 seconds with a standard deviation of 12.5 seconds. The amount of time Glenn can hold his breath underwater, G, is 105 seconds with a standard deviation of 10.9 seconds. Assume that D and G are independent random variables and X = D – G. What is the probability that on any given dive Dan holds his breath for less time than Glenn?

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.
