INSTRUCTIONS FOR QUESTIONS 1-5
For each of the following five questions, select the probability distribution
that could best be used to model the described scenario. Each distribution
might be used, zero, one, or more than one time in the five questions.
These scenarios are meant to be simple and straightforward; if you're an
expert in the field the question asks about, please do not rely on your
expertise to fill in all the extra complexity (you'll end up making the
questions below more difficult than I intended).
