Question

Suppose that a person who has recently helped start a band for the first time is randomly selected. The probability that the band will break up within 2 months is 0.5. Suppose we follow 11 bands (44 people) for 2 months and record the number of people whose band broke up. Why is the binomial model inappropriate for finding the probability that at least 11 of these 44 people will no longer be in that band within 2 months? List all the binomial conditions that are not met Select all that apply. A. The probability of success, p, is the same at each trial. B. The only two outcomes are success and failure C The trials are independent. D. There is a fxed number of trials: n

Explanation / Answer

C option is correct

In short: An experiment with a fixed number of independent trials, each of which can only have two possible outcomes. (Since the trials are independent, the probability remains constant.)
