A box contains 4 red balls and 3 blue balls. Four balls are selected simultaneously at random and their
colors are noted. A random variable X is defined to be the number of red balls minus the number of
blue balls. Find Pr[X = 2].

When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV^1.4 =C where C is a constant. Suppose that at a certain instant the volume is 570 cubic centimeters and the pressure is 91 kPa and is decreasing at a rate of 13 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at
this instant?
(Pa stands for Pascal – it is equivalent to one Newton/(meter
squared); kPa is a kiloPascal or 1000 Pascals. )

1. k + 6k = 8k - 4
2.10p - 14 - p = 4p - 9
3. x - 8x + 7 = 2x -11
4. 1/4x + 2/3 = x + 3/4
5. 1/2y - 2/3 = 2/3y + 1/2
6. 4/7p + 2/7p - 1 = 2/7p + 1/2
