Key Facts
- Expected Frequency = Probability × Number of trials
- Tells us what we would expect to happen on average
- Actual results may differ from expected results
- The more trials, the closer actual results get to expected results
- Used in business planning, quality control, and decision making
- Can be used with any probability (experimental or theoretical)
