## Chapter 3 Review, MATH 318

This is a list of topics likely to appear on the chapter 3 quiz. The quiz will cover key concepts and formulae -- you're expected to memorize the formula for finding the expected value of a discrete random variable, but not the more obscure formula for computing probabilities of Poisson distributions. This list is not guaranteed to be complete.
• Definitions/concepts: Random variables, discrete and continuous. Probability functions (discrete) and probability density functions (continuous). Expected value. Standard deviation. Binomial, Poisson, normal, standard normal, uniform and exponential probability distributions.
• Formulae: Expected value of a discrete random variable. Expected value of a binomial distribution. Standard deviation of a discrete random variable.
• Basic skills: Computing using complementary probabilities and using tables to look up probabilities. Computing probabilities given formulae for binomial distributions, Poisson distributions, and exponential distributions. Converting a random variable from normal to standard normal given the formula.
