Unit 7, Lesson 3, Investigation 1 and 2 Review
Standards and Benchmarks Covered in this Lesson
Develop an understanding of randomness and chance variation and describe chance and certainty in the language of probability.
Give a mathematical definition of probability and determine the probabilities of more complex events, and generate and interpret
Set: Student Quote and discussion (overhead: "Probability Distributions, wait times, independent events, what is all this
"We need to figure out what is going on here with Probability Distribution tables and graphs, and the relationship between
the two. And we need to talk about Rare Events."
Probability Distribution (Def)- at a glance tells the probability of all possible events.
? "Do we know how to display probability at a glance?"
? What have we done in the past?
(review)/Guided Practice: 2 examples on the overhead/board
v Rare Event (def)- any probability ≤ .05 or 5%
5) Check for
v Check Point Pg 500: class discussion
v M.O.R.E problems on their own in class
Practice: (modeling review above with student input)
v Recap the lesson for students'Tool Kits -Probability Distributions (graphs, tables, interpretations) and Rare Event
7) Finish M.O.R.E.S at home in review for quiz tomorrow.
