Answer:

b

Explanation:

When trail's of an experiment are independent then the outcome of one trial does not affect the probability of success on any other trial.

For example let two events be throwing of a dice and tossing a coin. The probability of getting a six on throw of a dice does not depend upon tossing of the coin( whether head or tail) As two are independent events.
