A survey-taker asks the age of each person in a random sample of 20 people. X is the age for the individuals.Does X have a binomial distribution?Yes.No, because the probability of success for each trial is not the same.No, because there is not a fixed number of trials.No, because the trials are not all independent.No, because there are more than two possible outcomes for each trial.
