Under which of the following conditions may binomial distribution be used?<br>I. The number of trials is infinite and <strong>NOT</strong> fixed.<br>II. The trials are independent.<br>III. Each trial has two possible outcomes.<br>Select the correct answer using the code given below.
- A. II only
- B. III only
- C. I and II
- D. II and III ✓
Correct Answer: D. II and III
Explanation
A binomial distribution is applicable under specific conditions: the number of trials (n) must be finite and fixed (which makes statement I incorrect), the trials must be independent (statement II is correct), and each trial must result in exactly one of two possible outcomes, usually termed success and failure (statement III is correct).
