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

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

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

6. 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.

7. 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?

8. 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?

9. 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?

10. Homework and next classes 1) pg 350 E#77 to 83 (skip #78) pg 354 AP #1 - 5 2) Sign up for a food, dessert, plastic ware, plates, cups, or drinks. You can collaborate on the food or dessert.
