Final answer:
To find the combined probability of two independent events occurring simultaneously, such as Nick oversleeping and having a pop quiz, one should multiply their individual probabilities, resulting in a 12% chance of both events happening on the same day.
Step-by-step explanation:
The question presents two independent events: Nick oversleeping with a probability of 48%, and Nick having a pop quiz with a probability of 25%. To find the probability of both independent events happening simultaneously, we multiply the probabilities of each event.
The probability of both events occurring is:
(Probability of oversleeping) × (Probability of quiz) = 0.48 × 0.25 = 0.12 or 12%.
Therefore, the answer is 12%, which corresponds to option 4.
