Which of the following is not a requirement for binomial distribution ?
Correct answer: D. Equally likely outcomes
- A. Constant Probability of Success
- B. Only two possible outcomes
- C. A fixed number of trials
- D. Equally likely outcomes
Explanation
The two outcomes need not be equally likely; they may have probabilities p and q with p different from q. Equal probabilities are required only for a symmetric binomial distribution, not every binomial distribution.
