Let X be a random variable with values in [0, 1] and let Y be a random variable with values in [0, 1, 2].
Initially, we have the following partial information about their joint probability mass function:
Y
0 1 2
X 0
1 1/8 1/8

Subsequently, we are provided with the following information:
(i) Given X = 1, Y is uniformly distributed.
(ii) p_(X|Y) (0|0) = 2/3.
(iii) E[Y |X = 0] = 4/5.
Use this information to fill in the missing values of the joint probability mass function table.

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.

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu
