MATH 399N Week 4 Discussion Topic; Discrete Probability Variables

Professor and Class,

A binomial experiment is a statistical experiment that has the following properties:

1. The experiment consists of n repeated trials

2. Each trial can result in just two possible outcomes. We call one of these outcomes a success and the other, a failure

3. The probability of success, denoted by P, is the same on every trial.

4. The trials are independent; that is, the outcome on one trial does not affect the outcome on other trials.

Consider the following statistical experiment. You flip a coin 2 times and count the number of times the coin lands on heads. This is a binomial experiment because

1. The experiment consists of repeated trials. We flip a coin 2 times.

2. Each trial can result in just two possible outcomes - heads or tails

3. The probability of success is constant - 0.5 on every trial.

4. The trials are independent; that is, getting heads on one trial does not affect whether we get heads on other trials
