Ms. smith puts a variety of wrapped chocolate candies into a bag. there are 5 sliver-wrapped candies, 1 purple-wrapped candies, 2 striped candies, and 4 golden wraped candies. if 15 students selected one candy at a time out of the bag without looking, and replace the candy after each draw, how many students would be expected to select a gold-wrapped candy from the bag

c) yes, because of asa or aas

it is 10.6 according to my calculations

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.
