Vocab Quiz/Thanksgiving Take Home!

Chapter 14 Vocab Quiz on Monday! Study! (definitions are in italics in case you were out!)

  • Probability (the likeliness of an event; the long run relative frequency of an event)
  • Law of Large Numbers (the idea that the long run relative frequency of an event settles down to the true probability as the number of trials increases)
  • Law of Averages (what does it suggest? remember, it's not true for independent events!)
  • Complement (the outcomes not in an event, A)
  • What should probabilities sum to?
  • OR (add)
  • AND (multiply)
  • NOT (subtract from 1)
  • Disjoint/Mutually Exclusive (events are disjoint/mutually exclusive if they have no outcomes in common, or no overlap; or, think, "they both cannot occur")
  • Independent/Independence (the outcome of one event does not affect the outcome of the next event; in other words, the probability of some event does not change)
  • Sample Space (the set of all possible outcomes in an event)
  • Equally Likely (events are equally likely if they have the same probability to occur)
  • Union (OR)
  • Intersection (AND)
Also, you have a take home quiz over Thanksgiving break! Feel free to get a head start this weekend since you only have to study vocab! If you didn't grab one in class (or were out), you can find it uploaded under our "Classroom Resources" link!
