Probability Distributions

Question:

Which of the following are true for the trials of a random experiment to be a Bernoulli's trial?

(A) There should be finite number of trials.
(B) The trials should be dependent.
(C) Each trial should have at least two outcomes.
(D) The probability of success remains same in each trial.

Choose the correct answer from the options given below:

Options:

(A), (B), (C) and (D)

(A), (B) and (C) only

(A), (C) and (D) only

(B) and (D) only

Correct Answer:

(A), (C) and (D) only

Explanation:

The correct answer is Option (3) → (A), (C) and (D) only

$\text{Bernoulli trial conditions:}$

$\text{Number of trials must be finite}.$

$\text{Trials must be independent}.$

$\text{Each trial has exactly two outcomes: success or failure}.$

$\text{Probability of success remains constant in each trial}.$

$\text{Correct options are (A), (C) and (D).}$
