Standard 5.0 Knowledge of Probability

Students will use experimental methods or theoretical reasoning to determine probabilities to make predictions or solve problems about events whose outcomes involve random variation.

Topic

A. Sample Space

Indicator

Objectives
  1. Describe the difference between independent and dependent events
  2. Determine the number of outcomes
    Assessment limit: Use no more than 5 dependent events with no more than 10 outcomes in the first event

Topic

B. Theoretical Probability

Indicator

Objective
  1. Express the probability of an event as a fraction, a decimal, or a percent
    Assessment limit: Use a sample space of 36 to 60 outcomes

Indicator

  • 2. Determine the probability of a second event that is dependent on a first event of equally likely outcomes
Objective
  1. Express the probability as a fraction, a decimal, or a percent
    Assessment limit: Use a sample space of no more than 60 outcomes

Topic

C. Experimental Probability

Indicator

Objective
  1. Make predictions and express the probability of the results as a fraction, a decimal with no more than 2 decimal places, or a percent
    Assessment limit: Use 20 to 500 results

Note: Highlighted assessment limits will be tested in the no calculator section of MSA. In the assessment limit, (0-10) or (-10 to 10) means all numbers in the problem or the answer will fall within the range of 0 to 10 (including endpoints) or -10 to 10 (including endpoints), respectively. All content standards are tested in MSA but not all objectives. Objectives that have an assessment limit are tested on MSA. Objectives without an assessment limit are not tested on MSA.
