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.
