A researcher estimates that 30 percent of students at his college would be willing to pay for Google Fiber, the high-speed, superfast Internet access. The researcher chooses a student at random and asks that student if she would pay. To simulate the outcome, the researcher could use one random digit as follows:

The correct answer is D because both simulations 2 and 3 are correct. In simulation 2, the digits 1, 2, and 3 represent "Yes," which means that 3 out of 10 digits (30%) represent a "Yes" outcome. In simulation 3, the digits 0, 1, and 2 represent "Yes," which also means that 3 out of 10 digits (30%) represent a "Yes" outcome. Therefore, both simulations 2 and 3 correctly represent the researcher's estimate that 30% of students would be willing to pay for Google Fiber.
