What you’ll learn
Estimate probability from repeated trials.
Key idea
Observed frequency is successes divided by trials; even all-success or all-failure finite data do not establish certain or impossible model events.
Finite observed all-success or all-failure does not prove certain or impossible model events; matched empirical frequencies do not remove uncertainty.
Worked example
Enter the exact value or ordered values in the format requested below.
A repeatable experiment records 16 successes in 40 trials. Enter its experimental probability as an exact number.
- The observed success fraction is 16/40=2/5.
- This empirical frequency estimates event chance under comparable repeated-trial conditions, not a proof of its exact model probability.
Answer: 2/5
