A fair coin has come up "heads" 10 times in a row. The probability that the coin will come up heads on the next flip is:

greater than 50%, it's due to happen.

less than 50%, since tails is happening so much.

About this resource

This AP Statistics Unit 6 Review covers probability theory and is designed for advanced 11th and 12th grade students enrolled in Advanced Placement Statistics courses. The quiz comprehensively assesses fundamental probability concepts including basic probability calculations, conditional probability, independent and dependent events, combinations of events using union and intersection operations, and the multiplication and addition rules. Students need a solid foundation in set theory, fraction operations, and logical reasoning to work through scenarios involving single events, compound events, and sampling with and without replacement. The problems require students to distinguish between independent and dependent situations, apply the gambler's fallacy concept, calculate probabilities using two-way tables, and work with geometric and binomial probability distributions. Mastery of these concepts demands understanding of when to multiply versus add probabilities, how replacement affects subsequent draws, and the ability to organize complex information into probability models. Created by James Dinkel, a Mathematics teacher in US who teaches grade 11-12. This comprehensive review quiz serves multiple instructional purposes throughout the probability unit, functioning effectively as guided practice during lessons, homework assignments to reinforce daily concepts, or formative assessment before the AP exam. Teachers can deploy individual questions as warm-up problems to activate prior knowledge or use question clusters to target specific probability concepts like conditional probability or independence. The varied question formats and real-world contexts make this quiz ideal for review sessions where students need exposure to the breadth of probability applications they'll encounter on the AP Statistics exam. This assessment aligns with Common Core standards S-CP.1 through S-CP.7, covering sample spaces, conditional probability, independence, and the rules of probability, while also supporting AP College Board learning objectives for Unit 4 (Probability, Random Variables, and Probability Distributions).
