Trials of a random experiment are called Bernoulli trials, if they satisfy certain condition. Which is the correct condition ?

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:

B and C only

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)
