Probability

BIG IDEAS:

(taken from “Big Ideas by Dr. Small”):

  1. Real-world situations can be represented using probabilities.
  2. Probability can be used to predict outcomes.
  3. Experimental probability and theoretical probability may differ due to chance.

STUDENT LEARNING GOALS:

GOAL #1: I can identify and communicate probabilities from real-world scenarios.

GOAL #2: I can determine all possible outcomes of an experiment

GOAL #3: I can make predictions based on theoretical and/or experimental probabilities.

CURRICULUM EXPECTATIONS:

  • Compare experimental probabilities with the theoretical probability of an outcome involving two independent events;
  • Research and report on real-world applications of probabilities expressed in fraction, decimal, and percent form (e.g., lotteries, batting averages, weather forecasts, elections);
  • Make predictions about a population when given a probability;
  • Represent in a variety of ways (e.g., tree diagrams, tables, models, systematic lists) all the possible outcomes of a probability experiment involving two independent events (i.e., one event does not affect the other event), and determine the theoretical probability of a specific outcome involving two independent events;
  • Perform a simple probability experiment involving two independent events, and compare the experimental probability with the theoretical probability of a specific outcome.
