11th Grade Independent and Dependent Events Quizzes

Center the lesson on one test: does knowing the first outcome change the probability of the second? Model this with replacement and without-replacement examples, then have students represent each situation numerically before applying a multiplication rule.

Mix identification questions with conditional-probability calculations and longer sequential-event problems. For example, students might compare two card draws with replacement to two draws without replacement, calculate both probabilities, and explain why the results differ.

Watch for students who confuse mutually exclusive events with independent events, treat without-replacement selections as independent, or reuse the original denominator after the sample space changes. Their written explanation should identify exactly how the first outcome affects the next probability.

Teachers can host a quiz as a digital quiz on Wayground or print the PDF for classroom practice and homework. Each quiz has a complete answer key; paper submissions can also be scanned or captured and graded through the Wayground for Teachers app.

Yes. Common Core high school probability develops independence through conditional probability: two events are independent when learning that one occurred does not change the probability of the other. This prepares students to analyze compound events and more advanced statistical models.

Give students who need processing support extended time and reduced answer choices in digital activities. Teachers can also create an alternate quiz with wider font spacing, while advanced learners receive problems involving several sequential events or less familiar contexts.

This collection is intended for Grade 11. The problems range from basic event classification to conditional probability and complex multi-step calculations suited to upper-high-school probability coursework.
