Which one is not a requirement of a binomial distribution? There are 2 outcomes for each trial There is a fixed number of trials The outcomes must be dependent on each other The probability of successes must be the same for all the trials.

Options

A. There are 2 outcomes for each trial
B. There is a fixed number of trials
C. The outcomes must be dependent on each other
D. The probability of success must be the same for all the trials

Explanation

To solve the question regarding the requirements of a binomial distribution, we will analyze each option provided:

1. **There are 2 outcomes for each trial**:
- In a binomial distribution, each trial must result in one of two outcomes, commonly referred to as "success" and "failure." This is a fundamental requirement of a binomial distribution.

2. **There is a fixed number of trials**:
- A binomial distribution requires a fixed number of trials (n). This means that the number of times the experiment is conducted is predetermined. This is also a fundamental requirement.
