Review Sheet for Test on Chapter 4

Terminology (30 points):

probability

sample space

probability distribution

conditional probability

disjoint events

event

outcome

independent events (plus know both tests)

random variable

discrete random variable

continuous random variable

expected value (mean of a random variable)

variance of a random variable

standard deviation of a random variable

law of large numbers (also know what it does not say)

Straightforward Techniques (30 points):

tree diagrams

computation of conditional probabilities ("common sense" method is OK)

answer questions regarding r.v. distributions (warning: Z-type questions are possible)

multiplication rule

addition rule

complement rule

combinations (e.g., complement rule with multiplication rule)

computation of means, variances, and standard deviations of complicated r.v. distributions

determining if probabilities are legitimate or form a probability distribution

Problem Solving (40 points):

Knowledge of dice, coins, lotto, numbers games, and cards is assumed. Problems will range from the mundane to the challenging. There will be nothing as difficult as the CONTRACT problem (counting the 2040 ways to make 5-character license plates), but you may be required to fill in a missing line or two in a problem of that level of complexity.
