Happy Thanksgiving!

First and foremost, happy Thanksgiving break! Enjoy your few days--rest up, relax, spend some quality time with friends and family, and recharge those academic batteries! When we come back we'll have 3 weeks (and a few more days) to power through the rest of probability!

Over break, please complete the following for homework:

• Venn Diagram practice problems!
• Remember, we can use Venn diagrams to model probability problems if we have an overlap, or "both" events occur--that's the key word that tells us we can use a Venn diagram!
• Also, remember if you are asked for "or," this includes "both"--for example, if I have to find the probability a person lives on campus or as a meal plan (1a), I do include the probability that someone has both...
• Use "Step by Step" example on page 347 for more help! Read the explanations on the left, they are likely more helpful than the formulas on the right!
• Or, google some "probability and Venn diagrams" for some more help!

• Normal Model/Probability AP Problem!
• The first part (a) is some Normal model review! Use last week's homework, the AP Stats guy, or your chapter 6 notes to help with this!
• For the second part (b), you have to use your answer from a to find an "at least one" probability, just like we saw on Tuesday's quiz!
• For part (c) you are asked to find a mean...here's some help...
• Use invnorm( to find the Z SCORE that has 99% of the data to the left of it (think about what you'll have to enter for the mean and standard deviation if you want a z-score!)
• Now, set up the z score formula...
• Substitute the value of the z-score with 99% of data below it, substitute your x-value (291.2), and then substitute the standard deviation--now solve for "x-bar!"

If you were out or lost the problems you can find them below. Be sure to have these done! I'm not sure if I'll check these each as a homework (each would count as it's own HW assignment), or collect and grade them--we'll see!

Finally, here's Monday night's textbook homework if you want to get a head start:

Page 362: 1, 5, 7, 19

• For 1, to define sample space you need to list all possible outcomes!
• For 19, use your "words" to write out each scenario--just remember, in this problem, when we take out a battery we have to adjust our fractions! This is done without replacement!

Monday HW = STUDY!

Tonight, STUDY! Tomorrow we will start class with 2 quizzes--our chapter 14 vocab quiz, and a chapter 14 math quiz! 

You will have roughly 20 minutes (25 max) to complete each of these; then we'll take a look at some Venn Diagram problems!

• For the "math quiz," study your textbook problems from throughout the week along with the multiple choice we did in groups!
• Here are some practice problems you can try to study your math:
• Page 342: 27, 28, 29, 30, 31, 32, 33, 34
• Answers to even practice problems:
• 28a. 0.057; 28b. 0.125; 28c. 0.001; 28d. 0.729; 28e. 0.784
• 30a. 0.0225; 30b. 0.092; 30c. 0.00008; 30d. 0.556
• 32a. 0.148; 32b. 0.6; 32c. 0.344
• 34. 0.469
• And here is your chapter 14 vocab list:
• Probability
• Sample Space
• Complement
• Intersection (know the symbol and that this means "AND" or "multiply")
• Union (know the symbol and that this means "OR" or "add)
• Law of Large Numbers
• Law of Averages
• Disjoint aka Mutually Exclusive
• Independent
• Equally Likely

Weekend HW!

This weekend, please complete the "Probability: The Basics Extension Questions" provided in class! 

• These questions are based on the questions/contexts from last weekend's homework--to get the probabilities/percentages you need, look at last weekend's homework or check the image below!
• You MUST do the challenge question to earn full credit! Use your notes! If you do no do this question you will earn half credit!
• Check your answers below!

On Monday we'll finish up chapter 14 and start chapter 15! Then, on Tuesday we'll have our chapter 14 vocab quiz and chapter 14 math quiz (20 minutes total), followed by some more chapter 15! See you there!

And here are the answers to your homework:

15a.) 0.353

15b.) 0.598

16a.) 0.896

17a.) 0.908

17b.) 0.60902

Thursday HW!

Tonight, please complete the "Normal Model Review" worksheet provided in class (or below). The answers are provided--your job is to show all of the appropriate work to get these answers! Use your chapter 6 notes for some help!

• So, you need to show...
• Shaded normal model, z-score(s), and normalcdf( 
• OR, show a shaded normal model with invnorm(

Tomorrow we'll finish up our chapter 14 notes with a math and vocab quiz coming on Tuesday! Enjoy your Thursday!

When's Day HW!

Tonight, please complete the following in your textbook:

Page 341: 21, 25, 29, 31

Tomorrow in class we'll continue to work through chapter 14, with the goal of finishing Friday! We will have our chapter 14 "math" quiz and chapter 14 vocab quiz coming up--I'm just not sure when yet!

Have an awesome Wednesday everyone! See you tomorrow!

2'sDay HW!

Tonight, please complete the below assignments in your textbook (more math practice)! I have listed both homework assignments (for today and tomorrow)--feel free to get a head start!

Tuesday HW = Page 340: 13, 19ab, 27

Wednesday HW = Page 341: 21, 25, 29, 31

Tomorrow we'll get back to our chapter 14 notes! See you there!

Monday HW!

Tonight, please complete the following (probability practice) in your textbook:

Page 340: 9, 11, 17, 23

• For #9 you have to check if the probability assignments are possible...
• Check: The probabilities should sum to 1 (since these are the only colors on the spinner)
• Check: We can't have any probabilities over 1 or any negative probabilities!
• So, if the probabilities are all less than 1, positive, and they sum to 1, then the probability distribution is possible

Tomorrow in class we'll continue to learn some probability stuff, and start to focus on vocabulary and some general concepts--see you there!

If you were out on Wednesday or Thursday be sure to make up your test by the end of the week!
