- HSS-CP.A.1 Describe events as subsets of a sample space (the set of outcomes) using characteristics (or categories) of the outcomes, or as unions, intersections, or complements of other events (“or,” “and,” “not”).
- HSS-CP.A.2 Understand that two events
*A*and*B*are independent if the probability of*A*and*B*occurring together is the product of their probabilities, and use this characterization to determine if they are independent. - HSS-CP.A.3 Understand the conditional probability of
*A*given*B*as*P*(*A*and*B*)/*P*(*B*), and interpret independence of*A*and*B*as saying that the conditional probability of*A*given*B*is the same as the probability of*A*, and the conditional probability of*B*given*A*is the same as the probability of*B*. - HSS-CP.A.4 Construct and interpret two-way frequency tables of data when two categories are associated with each object being classified. Use the two-way table as a sample space to decide if events are independent and to approximate conditional probabilities.
*For example, collect data from a random sample of students in your school on their favorite subject among math, science, and English. Estimate the probability that a randomly selected student from your school will favor science given that the student is in tenth grade. Do the same for other subjects and compare the results.* - HSS-CP.A.5 Recognize and explain the concepts of conditional probability and independence in everyday language and everyday situations.
*For example, compare the chance of having lung cancer if you are a smoker with the chance of being a smoker if you have lung cancer.*

- HSS-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. - HSS-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.
- HSS-CP.B.8 (+) Apply the general Multiplication Rule in a uniform probability model, P(A and B) = P(A)P(B|A) = P(B)P(A|B), and interpret the answer in terms of the model.
- HSS-CP.B.9 (+) Use permutations and combinations to compute probabilities of compound events and solve problems.
