Question

Suppose that the probability that a randomly selected person who has recently married for the first time will be divorced within 5 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 5 years is 0.30. Take a random sample of 10 people married for the first time and 10 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 4 of the 20 people in the sample will be divorced within 5 years? List all of the binomial conditions that are not met.

Explanation / Answer

A special discrete random variable is the binomial. We have a binomial experiment if ALL of the following four conditions are satisfied:

We can see that probability clause is not matching.
