Monday/Tuesday

For those of you who were out today, in class we:

• Looked at a "universal" application of tree diagrams with medical testing (stamp)
• Notes/discussion:
• How do we determine if events are independent using probability?

Tomorrow in class we'll do some AP FR and AP MC (in groups). Then, Wednesday it's on to chapter 16!

**We will have our chapter 15 vocab quiz to start class on Wednesday.**

Monday Homework: p. 363-366: 12, 24, 29, 33, 45

• This assignment is due/will be checked Wednesday!
• 12 and 24 are similar to 11, 21, 23a shown in the blog post below!
• For 24c look at today's notes about "equations and displays"--there are two ways you can approach this....
• For 29 try to use the independence formula....
• Does P(high BP) = P(high bp / high chol.)? That is, if we know someone has high cholesterol does it make them more/less likely to have high bp? 
• Or....
• Does P(high chol.) = P(high chol / high bp)? That is, if we know someone has high bp does it make them more/less likely to have high cholesterol?
• 33 = more independence formula
• Also, use the answers in the back of the book to help develop/strengthen your understanding for 29, 33
• Always check your answers/grade yourself for full credit! Here are 12, 24:
• 12a.) 0.62
• 12b.) 0.867
• 12c.) 0.194
• 12d.) 0.66
• *Note: b and c are conditional! And for d remember to pay attention to any overlap!
• 24a.) P(Canada given Mexico) = 0.444
• 24b.) No, going to Mexico and Canada are not disjoint; 4% of people have been to both.
• 24c.) P(Canada) = 0.19, and P(Canada/Mexico) = 0.444--Therefore, someone who has traveled to Mexico is more likely to go to Canada than a random person, so going to Canada/Mexico are not independent. 

Chapter 15 Vocab List: Quiz Weds

• All words from our ch. 14 quiz are free game! Especially....
• Equally likely events
• Disjoint/Mutually Exclusive
• Complement
• Sample Space
• Probability
• Law of Large Numbers
• Union
• Intersection
• Conditional Probability
• Independent Events
• Venn Diagram (when do we use it?)
• Tree Diagram (when do we use it?)
• Given 5 questions determine which do/do not require the use of conditional probability
• With replacement vs. without replacement
