A certain region has a population of 5.7 million. On any given day, the probability is StartFraction 1 Over 5000 EndFraction that a randomly selected resident decides to visit a certain amusement park. a. What is the probability that all the residents will decide to go tomorrow? b. What assumptions did you need to make to find that probability? a. Choose the correct probability.

after simplifying it i got: -36.25 as my answer. hope that !

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
