Question

one of the following consider as a bernoulli trials assumptions :

a. none of the above

b. for each trial there are only three possible outcomes

c. the probability of success is change from trial to trial

d. the trials are dependent

Explanation:

To determine the correct option, we recall the assumptions of Bernoulli trials:

1. Each trial has exactly two possible outcomes (success or failure). So option b (three outcomes) is incorrect.
2. The probability of success (denoted as \( p \)) remains constant from trial to trial. So option c (probability changes) is incorrect.
3. The trials are independent (the outcome of one trial does not affect the outcome of another). So option d (dependent trials) is incorrect.

Since options b, c, d are incorrect, the correct answer is a.

Answer:

a. None of the above
