A digital simulation records 30 successes in 100 trials. What is the relative-frequency estimate of success probability?
Show worked steps
Answer: 3/10
- Estimate = successes/trials = 30/100.
- This simplifies to 3/10.
- It is a simulation estimate, not an exact theoretical probability.
- 30 ÷ 100 = 3/10.
