B) The probability of success remains the same from trial to trial.
C) The value of π is equal to 1.50.
D) It approximates the Poisson distribution.

Question

Quizplus · Accepted Answer

The defining feature of a binomial distribution is that the probability of success (usually denoted as "p") remains constant across all trials. This is not the case for choices A, C, or D. While a binomial distribution can have more than two possible outcomes (choice A), it must have a fixed probability of success. Choice C is an impossible value for the parameter π (which is not typically used to denote the probability of success in a binomial distribution) as probabilities range from 0 to 1. Finally, choice D is incorrect as the Poisson distribution is a separate probability distribution from the binomial distribution, though they are related in some contexts.
