Question

Which of the following is a common characteristic of a binomial distribution?

A. There are more than two possible outcomes.
B. The probability of success is not the same in all trials.
C. There are infinitely many observations.
D. You should perform x trials until you observe a success.
E. Each trial is independent.

Answer 1

E. Each trial is independent

Explanation:

I'm not completely sure why all binomial distribution trials are independent, but there are requirements for binomial distributions.

These requirements are:

- Each outcome is either a success (p) or a failure (Q)

- All trials are independent

- There are a fixed number of "n" trials

- The probability of success (p) is the same for each trial

I also just took the test and got this right.
