This weekend, please complete the "Probability: The Basics" worksheet provided in class (or below). This homework assignment is your introduction to probability--the more work you put into this and the more learning you do independently, the easier your life will be in class! A few notes for your homework:
- All final answers should be written as decimals
- You must SHOW WORK for each question--the work may be as simple as a fraction, or adding/multiplying some fractions--but I need to see some work and then a circled decimal answer
- When you multiply or add fractions with your calculator (to get your decimal "final answer") be sure to put your fractions in parentheses! (Ex: (1/12) + (1/12))
- Feel free to read chapter 14 in your textbook to get a head start on this unit and for some examples!
- You can also watch some AP Stats Guy probability videos!
- Here are some examples you can use to help think about your own homework: this gives you some ideas for how to approach these problems, and also shows the type of work I need:
- And here are the homework questions in case you lost yours or were out:
- And finally, here are the homework answers so you can check yours!

- 0.0402
- Think: are the spins of the wheel independent? Does the outcome of one spin affect the outcome of the next spin? If so, the spins are related and are not independent; if the outcome of one spin does not affect the outcome of the next, then the spins are independent.
- Think: They got 64% by adding the two percentages (46% + 18%); does this seem reasonable?
- a. 1 b. P(both righty) = 0.7396, P(both lefty) = 0.0196 c. 0.103544 d. 0.310632
- ai. 0.51 aii. 0.55 bi. 0.041 bii. 0.84965 biii. 0.9744
And finally, there's this:
