The correct answer regarding the probability of the same event occurring twice is p^2. This expression arises from the fundamental rule of probability for independent events.

When considering the same event occurring twice, you essentially want to find the probability of that specific event happening on two separate occasions. If the event has a probability p of occurring on a single trial, then the probability of that event occurring in both trials (thus happening twice) is computed by multiplying the probability of it occurring in the first trial (which is p) by the probability of it occurring in the second trial (also p). Therefore, the probability of the same event happening in both attempts is represented as p * p, which simplifies to p^2.

Thus, it clearly illustrates how probabilities are calculated for independent events and highlights the significance of understanding basic probability concepts for evaluating events occurring multiple times.
