Statistics and Probability

Conditional Probability and the Rules of Probability

9-12.S-CP.1 - 9-12.S-CP.5 Understand independence and conditional probability and use them to interpret data.

BL

9-12.S-CP.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

BL

9-12.S-CP.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

BL

9-12.S-CP.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

BL

9-12.S-CP.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

BL

9-12.S-CP.5

Recognize and explain the concepts of conditional probability and independence in everyday language and everyday situations

9-12.S-CP.6 - 9-12.S-CP.9 Use the rules of probability to compute probabilities of compound events in a uniform probability model.

BL

9-12.S-CP.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

BL

9-12.S-CP.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

BL

9-12.S-CP.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

BL

9-12.S-CP.9

Use permutations and combinations to compute probabilities of compound events and solve problems

Using Probability to Make Decisions

9-12.S-CP.6 - 9-12.S-CP.7 Use probability to evaluate outcomes of decisions.

BL

9-12.S-MD.6

Use probabilities to make fair decisions

BL

9-12.S-MD.7

Analyze decisions and strategies using probability concepts
