Last homework assignment of the quarter (and the semester!)
I kinda rushed this (the tree diagram assignment provided in class)...so if you struggle, it's ok. Just do your best, and answer as many questions as you can. We will definitely be going over this tomorrow in class.
In case you lost it, here are the questions:
A private college report contains these statistics:70% of incoming freshmen attended public schools
75% of public school students who enroll as freshmen eventually graduate
90% of other freshmen eventually graduate
Create a tree diagram…
• What percent of freshmen eventually graduate?
• What is the probability that a student who attended public school graduates?
• What is the probability that a student who attended a non-public school graduates?
• What is the probability that a given graduate attended public school?
• What is the probability that a student who did not graduate attended a non-public school?
• Are graduation and public/other schooling independent? Explain.
Thank you so much to those of you who stayed after today! I truly appreciate all your hard work!

Hope to see more of you next week!

Tuesday!
Tonight, please complete the Venn Diagram practice problems provided in class.
This will be collected and graded as a 16 point AP Problem (techinically classwork) grade! Don't get a 0!
(1 point per answer (a,b, or c) and 1 point per Venn Diagram--you need 4).
Here are the questions in case you lost the paper...
Probability and Venn Diagrams
• Look for an overlap. If categories overlap (which means you’ll see the word “both”), then a Venn Diagram is often the best strategy to use.
1. A survey of college students shows that 56% live on campus, 62% have a campus meal plan, and 42% do both. What is the probability that a randomly selected student…
a. lives on campus or has a meal plan?
b. Lives in a residence hall but doesn’t have a meal plan?
c. Lives off campus and doesn’t have a meal plan?
2. Suppose the probability that a U.S. resident has traveled to Canada is 0.18, to Mexico is 0.09, and to both countries is 0.04. What’s the probability that an American chosen at random has…
a. Traveled to Canada but not Mexico?
b. Traveled to either Canada or Mexico?
c. Not traveled to either country?
3. Employment data at a large company reveal that 72% of the workers are married, 44% are college graduates, and half of the college grades are also married. What’s the probability that a randomly chosen worker…
a. Is neither married nor a college graduate?
b. Is married but not a college graduate?
c. Is married or a college graduate?
4. Real estate ads suggest that 64% of homes for sale have garages, 17% have both a garage and a pool, and 32% have neither a garage nor a pool. What is the probability that a home for sale has…
a. A pool or a garage?
b. A pool but no garage
c. A pool or a garage but not both?
This will be collected and graded as a 16 point AP Problem (techinically classwork) grade! Don't get a 0!

Quiz Tomorrow!
We will have a probability quiz tomorrow! Nothing from your weekend homework or today in class. The quiz will be either version B or C--we did Quiz A in class in groups. I handed out the answers, so just study these and you'll be good to go!
Also, tonight please complete the following:
page 342: 27 (also practice for the quiz)
page 362: 1, 17, 25
I plan to have a review session at noon on either Monday or Tuesday where I'll buy pizzas and we'll all study. Please vote for a day (don't vote if you're not going to come).
And don't forget--Saturday Session is this week! Great time to review for the midterm!

Weekend HW
One more week until exams...
I'll give you a copy of what's on your exam (and the format) on Monday.
This weekend, please complete the following (contingency tables are back!):
page 362: 7 - 11, 27 (*Hint: If events are disjoint, they cannot be independent; and if they are independent, they cannot be disjoint*)

Thursday!
Currently jamming to the new Bruno Mars album. Pretty fantastic if you need some good pop music in your life. I think "Treasure" is my current favorite...
Anyway, onto some homework (for you to enjoy while listening to Bruno Mars).
Tonight, please complete:
p. 340: 18, 19, 29, 31, 33
Gotta love the revival of (actual) mathematics in this class!

Back to real life....
Back to the grind...
Tonight, please complete the following:
Page 339: 5, 7, 9, 11, 13, 17
Over the next 8 days we'll cover probability, hopefully chapters 14 and some of 15. We will not review for our exam in class; instead, I will be available next week after school and we have our Saturday session (1/12)! I'm glad to be back! Enjoy your first night of homework!
