Handling Data - Probability

  1. Step 1
     

  2. Step 2
     

  3. Step 3
     

  4. Step 4
    Discuss the chance or likelihood of particular events. View step.

     
    Use the language associated with probability to discuss events, including those with equally likely outcomes. View step.

  5. Step 5
    Understand and use the probability scale from 0 to 1. View step.

     
    Find and justify probabilities based on equally likely outcomes in simple contexts. View step.

  6. Step 6
    Know that if the probability of an event occurring is p, then the probability of it not occurring is 1 – p. View step.

     
    Estimate probabilities from experimental data; understand that:
    • if an experiment is repeated, there will be different outcomes;
    • increasing the number of times an experiment is repeated generally leads to better estimates of probability.
    View step.

  7. Step 7
    Find and record all possible mutually exclusive outcomes for single events and two successive events in a systematic way. View step.

  8. Step 8
    Know that the sum of probabilities of all mutually exclusive outcomes is 1, and use this when solving problems. View step.

     
    Use a single probability to find an estimate of frequency. View step.

     
    Find an estimate of the frequency for up to two events. View step.

  9. Step 9
    Understand relative frequency as an estimate of probability and use this to compare outcomes of experiments. View step.

  10. Step 10
    Find the probability of two or more mutually exclusive events occurring. View step.

     
    Find the probability of two independent events occurring. View step.
