choices:
random and biased
random and unbiased
nonrandom and biased
nonrandom and unbiased

two major points about the sample she took:
- she wants to know info about the general population who will be at the theatre that night, but notice where she took her sample - parents who had kids at rehearsal. is this an unbiased, or biased sample?

- she took the first 25 parents - is this random, or not?
