Previous Expected Frequency Next Mutually Exclusive Events
  • The results of a probability experiment will change each time it is performed
  • The relative frequencies calculated from each experiment will also change
  • The more trials there are in an experiment, the more similar the results will be when the experiment is repeated
  • The probability of a random outcome doesn't change depending on previous outcomes
  • The more trials there are in an experiment, the closer the relative frequency will be to the true probability
  • The more trials we perform in a probability experiment, the less deviation is expected from the true theoretical probability
  • Experiments with more trials have frequencies that are closer to their expected frequencies
  • The expected frequency is calculated by multiplying the number of trials by the theoretical probability of the outcome
