2.14 - Probability
The student will
- use data
from probability experiments to predict outcomes when the experiment is repeated.
UNDERSTANDING THE STANDARD
- A spirit of
investigation and experimentation should permeate probability instruction,
where students are actively engaged in investigations and have opportunities to
- 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
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.
