Read This! (Weds HW, Thurs HW, Next Week's Tests...)

Tonight, please complete the half sheet provided in class today (or below)! The homework answers are also provided in red on the image below so you can check!

1. First, read each question and label it as "binomial" or "geometric" (B or G) probability.
2. Then, calculate each probability!
1. Use any method that works but...
2. Try to use "geometpdf" and "binompdf" for practice!
3. Some helpful hints...
1. Question a was not covered in class today! Think about this...if 20.1% of Americans speak a language other than English at home, how many people do we think we'll survey until we actually find a person who speaks a language other than English at home?
1. If you want some more specific help, check out "The Geometric Model" on page 387 of your book, or look at the "Step-by-Step" example on page 389!
2. Questions b and c are very much like the 3 problems we did today in class! Use questions a-c from today's notes to help! Or check out the TI tips on page 389-390 (geometric) or page 393 (binomial)!
3. Question d--this is an extension of what we learned today in class--it's like 3 "part a's" from today's notes combined into one problem....OR means add, so we'll have to find some probabilities and add them...
4. Questions e and f are problems we've dealt with before, but now we can use the graphing calculator to do these more quickly (and hopefully more simply); many of us will probably do some subtraction here...think about what "numbers of successes" the question is asking for; then, think about what "numbers of successes" are NOT included; find those probabilities, and then subtract from 1!

And here's tomorrow (Thursday) night's homework--you can't do it all yet, but you can definitely get a head start!

Finally, here's the plan for our tests next week--read this information below, and consider your schedule! If you know you will not be here, then be sure to make time to make up your test BEFORE break! It will not be a good idea to make the test up when you return! That might mean staying after, coming during study hall, or coming before school even--do whatever you need to do so you don't have a test looming over your head after break!

• Goal: finish chapter 17 on Friday
• Monday
• probability review and chapter 17 wrap-up (I will also be after school on Monday to study for the test!)
• Tuesday
• probability math test
• Wednesday
• probability vocab test (and some open-note multiple choice)
• Thursday (1/2 day)
• Students who have done both tests will use this time to start their winter-break take home test!
• Students who were out caroling (or just out) on Wednesday will do their vocabulary test on Thursday!
• If you are out Tuesday you WILL NOT have enough time to do the "math test'" on a half day, so you will have to make time to do the test after school Monday, during study hall on Monday/Tuesday/Wednesday, or after school Tues or Weds
• If you are out both Tuesday and Wednesday you will do the vocab test on the half day (Thursday) but will have to make time to do the math test (Monday?)
• If you are leaving next week and will be out all week, or the above scenarios don't work for you, please come talk to me about your situation outside of class! Be proactive/responsible!
