Final answer:
A binomial probability experiment requires a fixed number of trials, independent trials, and a constant probability of success.
Step-by-step explanation:
A binomial probability experiment must satisfy the following criteria:
Fixed number of trials: There must be a set number of trials, denoted as 'n'. This means that the experiment is repeated a specific number of times.
Independent trials: Each trial must be independent of the others, meaning that the outcome of one trial does not affect the outcome of another trial.
Constant probability of success: There are only two possible outcomes for each trial, called success and failure. The probability of success, denoted as 'p', should remain the same for all trials.
