Answer:
the answer is below
Step-by-step explanation:
We have the total number of possible samples = 4 * 4 = 16 (As 4 choices for each value)
in addition we have to as all sample occur with equal probability, probability of each sample = 1/16, below is samling distribution of mean
x1	x2	probabilityP(x1,x2)	sample mean
190	190    1/16                 190
190	100    1/16                 145
190	272    1/16                 231
190	74    1/16                 132
100	190    1/16                 145
100	100    1/16                 100
100	272    1/16                 186
100	74    1/16                        87
272	190    1/16                 231
272	100    1/16                 186
272	272    1/16                 272
272	74    1/16                 173
74	190    1/16                 132
74	100    1/16                 87
74	272    1/16                 173
74	74    1/16                 74
Summarizing above with adding duplicate values
sample mean   probability
        74              1/16
       87               1/8
     100                1/16
     132                1/8
     145                1/8
     173                1/8
    186                1/8
    190               1/16
     231               1/8
    272               1/16

Answer: 
The volume(V) of gas will increase when the pressure of the gas decreases assuming all the other variables are held constant.
Step-by-step explanation:
  P = Pressure of the ideal gas
             V = Volume of the ideal gas
             n = Moles of the ideal gas
             R = Universal gas constant
             T = Temperature of the ideal gas
