Tonight please complete the following problems from your textbook--these are the same problems that are on the printout provided in class!

Page 366: 35/37, 39/41, 43, 45

• This homework assignment gives us another night of practice with all this conditional probability and tree diagram stuff!
• Here are the answers so you don't have to use your book (you'll also get a key tomorrow with all of the work shown)....
• 35a) No, leaving on time and the luggage making the connection are not independent; the luggage is more likely to make the connection if the flight is one time (the probability is higher).
• 35b) 0.695
• 37) 0.975
• 39a) No, absenteeism is not independent of shift worked; the probability of being absent for night employees is double that of employees on the day shift.
• 39b) 0.014 = 1.4%
• 41) 0.571 = 57.1%
• 43a) 0.20
• 43b) 0.272
• 43c) 0.353 
• 43d) 0.033
• 45) 0.563

This weekend you will have a "probability review" homework assignment that recaps many of the ideas we've covered so far (a little studying after two chapters). If you're feeling crazy and want to get a head start tonight, here are the problems:

Tomorrow in class we'll do a bunch more AP problems (MC and FR) that will be collected and graded as classwork! See you there! 

And here's the outline of our course through midterm exams in case you're curious...

Thursday (12/7) = Chapter 15 Vocab Quiz, Tree Diagram Practice (HIV Testing, Hurricane Katrina)

Friday (12/8) = Chapter 15 Classwork (AP MC and FR)

Monday (12/11) = Start chapter 16!

Tuesday (12/12) = Chapter 15 Quiz (15 min) and Chapter 16 Notes

Tuesday (12/19) = Probability Test: Chapter 14, 15, 16

Wednesday (12/20) to Friday (12/22) = Geometric and Binomial Probability (mini-test Friday 12/22)

Winter Break = "Teaching Yourself Chapter 13--Experimental Design" Project

Tuesday (1/2) to Friday (1/5) = Recapping Experimental Design

Monday (1/8) to Friday (1/12) = Midterm Exam

And lastly, one of our classmates lost a necklace that's very important to them--if you see this necklace anywhere (including on a person) please let me know!
