What to Focus On
- An experiment produces well-defined outcomes.
- An outcome is a possible result of an experiment.
- A coin toss has two outcomes: H and T.
- Empirical probability comes from actual trials.
- P(E) = Number of trials in which the event happened / Total number of trials.
- Probability = Number of favourable outcomes / Total number of outcomes.
- Use the total number of trials as the denominator.
- For groups of outcomes, add the matching frequencies first.
- A probability can be written as a fraction in simplest form.
Common Mistakes to Avoid
An outcome and an event are the same thing.
Probability is found by dividing by the number of favourable outcomes only.
The number of trials and the number of favourable outcomes mean the same thing.
Memory Tips

Measure of uncertainty
Outcome in a coin toss
