Probability!
Halloween is a scary time: monsters, ghouls, goblins, and ... scariest of all ... the probability unit of AP Stats.
Thankfully, we've got you covered. Our probability lessons bring in relevant contexts, intuitive explanations, and basic rules and methods for solving probability problems (rather than confusing formulas).
We've also made some important updates in recent years, including revamping a lesson to explore the fun context of the "curse" of the home run derby. The lesson is available in both standard and activity-based formats. Check it out below.
Let's skew it!
Home Run Derby “Curse”
Lesson 5.1
Introduce students to probability by exploring the "curse" of the home run derby. Lesson comes in standard and activity-based formats.
The 5 Intuitive Probability Rules for a 5
Lesson 5.3
Rather than a confusing mess of formulas, these rules (summarized at the end of Lesson 5.3) provide a simple set of guidelines for students, as they dive deeper into AP-level probability questions:
Draw first (Venn, Table, Tree)
Complement rule: P(A') = 1 – P(A)
“Or” means add, beware of double-counts
“Given” means divide by the given
“And” means multiply, adjust for dependence
