2.14 - Probability

The student will 

  • use data from probability experiments to predict outcomes when the experiment is repeated.

Adopted: 2016


  • So that I can use the data generated from experiments to make and prove predictions
  • So that I can understand that determining the likelihood of an event is predicting the probability of it happening
  • So that I can learn to be able to make valid/close predictions in sports based on past performance


  • A spirit of investigation and experimentation should permeate probability instruction, where students are actively engaged in investigations and have opportunities to use manipulatives.
  • Investigation of experimental probability is continued through informal activities, such as dropping a two-colored counter (usually a chip that has a different color on each side), using a multicolored spinner (a circular spinner that is divided equally into two, three, four, six or eight parts where each part is filled with a different color), using spinners with numbers, or rolling random number cubes.
  •  Probability is the chance of an event occurring.
  • An event is a possible outcome in probability. Simple events include the possible outcomes when tossing a coin (heads or tails), when rolling a random number cube or when spinning a spinner.


The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to

  • Conduct probability experiments using multicolored spinners, colored tiles, or number cubes and use the data from the experiments to predict outcomes if the experiment is repeated.
  • Record the results of probability experiments, using tables, charts, and tally marks.
  • Interpret the results of probability experiments.
  • Predict which of two events is more or less likely to occur if an experiment is repeated.
