Questions to be Sure to Include

Many of the learning targets can be addressed within a single context. Create a context with a nice probability distribution and you can ask several questions within that context.

One contextual question that deals with transforming and combining random variables. I like the temperature conversion from Fahrenheit to Celsius for transforming variables and monthly sales for combining random variables.

One question where students have the option of using a binomial distribution or a normal approximation to calculate a probability. Let them choose which approach and give full credit for both approaches (just make sure they check the Large Counts condition if they use the Normal approximation.)

One inferential thinking question. So maybe students use the binomial distribution to figure out the probability a free throw shooter makes 9 or more free throws out of 10 and then assess whether this happening would be convincing evidence that a player shoots better than 60%.

Don’t be afraid to ask a Chapter 5 probability question on this test if it fits.

At least one old AP question. There are many to choose from and they are very accessible for students after completing this chapter.
Tips to Give Your Students

Close reading and careful writing are critical to your success this year.

Be sure to answer all parts of each question.

There are a lot of formulas in this Chapter. Don’t memorize them. Understand them.

Don’t use binompdf as your “work” for a free response. Use the binomial formula.

Do use binomcdf as your “work” for a free response. Just be sure to identify the distribution as binomial along with the two parameters n and p.

Be able to tell when a situation calls for a binomial distribution, a geometric distribution, or a Normal distribution.
