Questions to be Sure to Include

One question which asks students to set up a simulation (they don’t need to actually do the simulation…this can be a nightmare to grade).

A large twoway table (more than 2 rows and 2 columns) can be a great context to ask a variety of questions: probability, joint probability, conditional probability, complement events, independence of two events, mutually exclusive.

A problem where some information is given in words and students can choose whether to use a Venn Diagram, a twoway table, or a formula to answer the question.

One question in which students can use a tree diagram. This question should have two parts: one that requires students to add two or more probabilities and one that asks students to find a conditional probability.

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.

Use your list of strategies first. Rely on formulas last.

Show your work. For probability questions, this does not mean showing a formula–you need only show numbers. Most of the time a fraction and then the decimal equivalent is sufficient (i.e. 15/32 = 0.47). If this student only wrote 0.47 they would not get full credit on the AP Exam (naked answer).

If you are struggling to remember a concept, always go back to the context of the Activity where you learned the idea:

Mutually exclusive events: Brown Eyed Female

Independent events: English or Math

Tree Diagrams: Pair of Aces


The best way to get better at probability questions is to do more probability questions.
