Which of the statement are true for Bernoulli trials?

Both 1& 3

Bernoulli Trials Many random experiments that we carry out have only two outcomes that are either failure or success. For example, a product can be defective or non-defective, etc. These types of independent trials which have only two possible outcomes are known as Bernoulli trials.

Bernoulli trials, must satisfy these conditions:

1. The number of trials should be finite.

2. The trials must be independent.

3. Each trial should have exactly two outcomes: success or failure.

4. The probability of success or failure does not change for each trial.
