In a binomial distribution
A) the number of trials n must be at least 30.
B) the random variable X is continuous.
C) the results of one trial are dependent on the results of the other trials.
D) the probability of success p is stable from trial to trial.

Question

Quizplus · Accepted Answer

In a binomial distribution, the probability of success (p) is stable from trial to trial, which means that the outcome of one trial does not affect the outcome of the other trials. The number of trials (n) can be any positive integer, and the random variable (X) represents the number of successes in these n independent trials. The binomial distribution is a discrete probability distribution, where X can only take on integer values. Therefore, option A and B are incorrect. Option C is also incorrect since the results of one trial are independent of the results of other trials.
