  2. Goal of Probability Using Math to model certain situations, we seek to find the likelihood of a certain event happening (or not happening) From this we can do the following: Using known data of a certain event, we determine the likelihood of it occurring. (and how likely our guess is correct or incorrect)

  3. Important Terminology • Event, Simple event, Sample Space pg.139 • Notation for probability pg.139-140 • Values of a probability pg.144 • Complement of an event pg.144 • Actual odds against / in favor, etc. pg.147 • Compound event pg.152 • P(A or B), P(A and B) pg.152 • False Positive, True Negative (table 4-1) pg.153 • Disjoint (mutually exclusive) events pg.154 • P(A and then B) (when A occurs first, then B occurs)pg.159 • Independent & Dependent events pg.162 • “at least one” & Conditional Probability pg.161

  4. Important Concepts • Venn Diagrams pg.155–156 • Addition rulepg.154 • Rule of Complementary Events pg.156 • Multiplication Rulepg.162 • Conditional Probabilitypg.173 • Rare Event Rule pg.138 • Rule of Large Numbers pg.141 • The 5% Guideline pg.164
