STP 231 Study Guide - Midterm Guide: Mutual Exclusivity, Contingency Table, Conditional Probability
Document Summary
If probability of a and b (p(a&b)) are equal to 0, then they are mutually exclusive. Contingency table: see midterm practice question #1. Word problem: see midterm practice question #2. Probability tree: see midterm practice question #7. In addition, go through the problems in the lecture slides for sections 3. 1 to 3. 3. Entire area under a density curve is 1. Density curve is always on or above the horizontal axis. Discrete random variables are not the same, so greater than and equal is not the same as greater than. Continuous random variables are the same, so greater than and equal to is the same as greater than. Given the probability distribution of a random variable x, find probabilities and mean x. Bernoulli trial: a trial that has two possible outcomes. Binomial experiment: an experiment that consists of a series of independent bernoulli trials.
