Predicting the Future
If you flip a coin 100 times, how many heads would you expect? If a factory produces 1000 items and the probability of a defect is 0.02, how many defective items should they expect? Expected frequency helps us make predictions about what should happen in the long run.
This concept bridges the gap between theoretical probability and real-world planning.

Practice Questions for Expected Frequency
Which formula correctly gives the expected frequency of an event?
A fair coin is flipped 50 times. The expected number of heads is 25. In the actual experiment, only 18 heads are recorded. Explain why the actual number of heads may differ from the expected number of heads.
