Statement I is true because if two events are independent, the outcome of one event has no impact on the outcome of the second event. For example, if a coin is flipped twice, the first outcome does not affect the second outcome.
Statement II is also true because if two events are dependent, the occurrence of one event affects the occurrence of the second event. For example, if a card is drawn from a deck and not replaced, the probability of drawing a certain card changes for subsequent draws. Therefore, both statements are true for probability analysis, making option C the correct answer.
