For spirit day, each 8th-grade homeroom designs a unique two- color t-shirt. they get to choose from the colors red (r), blue (b), green (g), violet (v), and orange (o). each t-shirt is a solid color with a different color used for the student's name. what is the probability that a homeroom will have a t-shirt with a combination of blue and violet? (a) p(b and v)=10% (b) p(b and v)=20% (c) p(b and v)=30% (d) p(b and v)=40%

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
