suppose that the probability that a randomly selected person who has recently married for the first time will be divorced within 2 years is 0.2 and that the probability that a randomly selected person who has recently married for the second time will be divorced within 2 years is 0.4 Take a random sample of 25 people married for the first time and 25 people married for the second time. The sample is chosen such that no one in the sample is married to anyone else in the sample. Why is the binomial model inappropriate for finding the probability that exactly 8 of the 50 people in the sample will be divorced within 2 ​years? List all of the binomial conditions that are not met. Select all that apply.     A. There are a fixed number of​ trials: n.   B. The probability of​ success, p, is the same at each trial.   C. The trials are independent.   D. The only two outcomes are success and failure.
