The student will represent probabilities as fractions and decimals between 0 and 1 (inclusive), and as percentages between 0% and 100% (inclusive), and verify that the probabilities are reasonable.


In 2007 mathematics standards, the concept of probability is introduced for the first time in 7th grade.


  • Item Type(s): This benchmark may be assessed using: MC item(s)

  • Clarification :
    Students will determine the likelihood or probability of an outcome occurring.

    Students will verify that probabilities are reasonable.

    Students will determine the outcomes of an experiment or test.
  • Content Limits :
    Items may include concepts such as certain, impossible, likelihood, fair, unfair, most likely, equally likely, and least likely.

    Items will include only simple events.

    Items may include representing probabilities as fractions, ratios, decimals between 0 and 1 (inclusive), and/or percentages between 0 and 100 (inclusive).

    Items will not include combinations or permutations.

    In items involving the determination of all possible outcomes, the number of outcomes should not exceed 36.
  • Stimulus Attributes :
    Items should be set in a real-world or mathematical context.

    Graphics should be used in some of these items, as appropriate.


  • Test Item #: Sample Item 1
  • Question: Mrs. Davis is teaching her class about probability. She prepared the set of golf balls listed below.
    • 6 red golf balls, each labeled with a different number from 1 to 6
    • 7 green golf balls, each labeled with a different number from 1 to 7
    • 8 blue golf balls, each labeled with a different number from 1 to 8
    • 9 yellow golf balls, each labeled with a different number from 1 to 9

    Mrs. Davis put all the golf balls into a sack and mixed them up. Nancy will be the first student to select a golf ball from the sack without looking. Which of the following outcomes is most likely to occur?
