Warm-up 5.5 Independent Events Jack and Jill have finished conducting taste tests with 100 adults from their neighborhood.

Review H.W. 4.3 E#46, 50 and 51

Important formulas Mutually Exclusive (Disjoint) Non-Mutually Exclusive Independent For any two events

D. 25 pg 340 Suppose you choose a student at random from your school. In each case, does knowing that event A happened increase the probability of event B, decrease the probability of event B, or leave the probability of event B unchanged? a. A:The student is a football player; B: The student weighs less than 120 lb. b. A: The student has long fingernails; B: The student is female. c. A:The student is a freshman; B: The student is male.d. A: The student is a freshman; B: The student is a senior

Examples using formulas Example: At a particular college, 56% of students lived on campus, 62% have campus meal program, and 42% do both. L = {students living on campus); M= {students with a campus meal plan} a.Are these events disjoint? b. Are these events independent?

Another Example Another Example: Police report that 78% of suspected drunk drivers pulled over are given a breath test, 36% a blood test, and 22% both tests. L = {suspected drunk drivers that given blood test} R = {suspected drunk drivers that are given a breath test} a.Draw a two-way table of the data. b. Are the events mutually exclusive? c. Are the two tests independent?

Final Example Final Example: In a statistics textbook 48% of pages had data displays, 27% of pages had an equation and 7% of pages had both a data display and equation. a. Draw a two-way table of the information. b. What is the probability that a randomly selected page with an equation, also had a data display?

Homework and next classes 1) pg 350 E#77 to 83 (skip #78) pg 354 AP # ) Sign up for a food, dessert, plastic ware, plates, cups, or drinks. You can collaborate on the food or dessert. Food means (anything not sweet) Up to 3 people can sign up for drinks. Please discuss what you plan to bring so we have a variety of beverage choice (tea, soda, juice) 3) Remember we will be having our holiday potluck December 13 th. The same day as our Ch. 5 Test. Notebook Check: 5.1 Warm-up,5.1, 5.2 and 5.3, 5.4 Day 1, 5.4 Day 2, notes at 16 pts each ( 10 pts for notes and 6 pts for warm-up) = 80 pts About 20 vocab terms for 20 pts
