S-CP.B.6 Find the conditional probability of A given B as the fraction of B‘s outcomes that also
belong to A, and interpret the answer in terms of the model.
S-CP.B.7 Apply the Addition Rule, P(A or B) = P(A) + P(B) - P(A and B), and interpret the answer in
terms of the model.
Instructional Days: 7Student Outcomes
Lesson 1: Chance Experiments, Sample Spaces, and Events
● (^) Students determine the sample space for a chance experiment.
● (^) Given a description of a chance experiment and an event, students identify the
subset of outcomes from the sample space corresponding to the complement of
an event.
● (^) Given a description of a chance experiment and two events, students identify the
subset of outcomes from the sample space corresponding to the union or intersection
of two events.
● (^) Students calculate the probability of events defined in terms of unions, intersections,
and complements for a simple chance experiment with equally likely outcomes.
Lesson 2: Calculating Probabilities of Events Using Two-Way Tables
● (^) Students calculate probabilities given a two-way table of data.
● (^) Students construct a hypothetical 1000 two-way table given probability information.
● (^) Students interpret probabilities in context.
Lesson 3: Calculating Conditional Probabilities and Evaluating Independence Using Two-Way
Tables
● (^) Students construct a hypothetical 1000 two-way table from given probability
information and use the table to calculate the probabilities of events.
● (^) Students calculate conditional probabilities given a two-way data table or using a
hypothetical 1000 two-way table.
● (^) Students interpret probabilities, including conditional probabilities, in context.
Lesson 4: Calculating Conditional Probabilities and Evaluating Independence Using Two-Way
Tables
● (^) Students use a hypothetical 1000 two-way table to calculate probabilities of events.
● (^) Students calculate conditional probabilities given a two-way data table or using a
hypothetical 1000 two-way table.
● (^) Students use two-way tables (data tables or hypothetical 1000 two-way tables) to
determine if two events are independent.
● (^) Students interpret probabilities, including conditional probabilities, in context.
Lesson 5: Events and Venn Diagrams
● (^) Students represent events by shading appropriate regions in a Venn diagram.
● (^) Given a chance experiment with equally likely outcomes, students calculate counts
and probabilities by adding or subtracting given counts or probabilities.
● (^) Students interpret probabilities in context.
