A. There should be infinite number of trials.
B. The trials should be independent.
C. Each trial has exactly two outcome; success and failure.
D. The probability of success changes in each trial.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
Bernoulli trials satisfy the following conditions:
• Each trial has only two possible outcomes (success or failure).
• The trials are independent.
• The probability of success remains the same in each trial.
Check the options:
(A) Infinite number of trials → not required.
(B) Trials should be independent → correct.
(C) Each trial has exactly two outcomes → correct.
(D) Probability of success changes in each trial → incorrect.
final answer: (B) and (C)
