Answer: Rare events in continuous time/space (e.g., calls per hour, defects per meter).
- A A fixed, predetermined number of independent Bernoulli trials each time
- B Rare events in continuous time/space (e.g., calls per hour, defects per meter)
- C Large samples specifically, where the normal approximation applies best
- D Symmetrical distributions centred specifically and exactly at the mean
Correct answer: B. Rare events in continuous time/space (e.g., calls per hour, defects per meter)
Explanation: Poisson: models rare independent events in fixed time/space. Parameter lambda = mean rate.
