Description: Determine whether the binomial distribution is an appropriate model for the probability distribution of the given experiment. Randomly interview 200 students about whether they favor a campus issue and count the number of yes responses. Assume that none of the students interviewed refuses to answer the question.

Key Concepts

Binomial Distribution

The binomial distribution models the number of successes in a fixed number of independent trials, each with the same probability of success. It is suitable for experiments where each trial results in one of two mutually exclusive outcomes, often labeled as 'success' and 'failure'.

Fixed Number of Trials

A key characteristic of a binomial experiment is that the total number of trials is predetermined and does not vary. This ensures that the total number of opportunities for a success is constant.

Binary Outcomes

Each trial in a binomial experiment can result in only one of two outcomes, such as 'yes' or 'no'. This dichotomy is essential for modeling the events using the binomial distribution.

Independent Trials

The assumption of independent trials means that the outcome of any individual trial does not affect the outcomes of the others. This ensures that the probability of success remains constant across all trials.
