Jenny is dog sitting for 13 dogs. There were 3 Labradors (L), 2 Golden Retrievers (G), 3 Dalmatians (D), 4 terriers (T), and 1 bulldog (B) in the original group. A stray Golden Retriever joins the group. In an experiment in which Jenny picks a dog breed from the group at random, how does this change the size of the sample space from an earlier experiment Jenny did before the new Golden Retriever arrived?

A. It makes it larger, because there are more dog breeds.

B. It makes it larger, because there are more possible outcomes.

C. It does not change, because the number of outcomes remains the same.

D. It does not change, because the population remains the same.

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?
