Question

which of the following is a requirement for a binomial experiment? a. more than two outcomes per trial b. each trial has only two possible outcomes c. probability of success varies from trial to trial d. trials must depend on each other

Explanation:

A binomial experiment has the following requirements:

• Fixed number of trials.
• Each trial has only two possible outcomes (success or failure).
• Probability of success is the same for each trial.
• Trials are independent.

Option a is incorrect as binomial requires two outcomes. Option c is wrong because probability of success is constant. Option d is incorrect as trials are independent. Option b is correct as each trial in a binomial experiment has only two possible outcomes.

Answer:

B. Each trial has only two possible outcomes
